Rogersia plant. Rogersia, planting and care in open ground. Caring for exotic Rogers

A true owner and an inveterate gardener is always haunted by the desire to plant some exotic and original plant on his property. Such an intention can evoke a range of positive emotions in a person and significantly lift the mood of the owner of the land plot. But most of the plants from exotic regions that are on the market are quite capricious to care for and require systematic care. In most cases, having spent a decent amount of money, the gardener does not even have time to admire the bright blooms. The plant, contrary to the seller’s promises, quickly dies and does not stay on the site during one flowering cycle. As a result, an empty space appears in the garden bed. But there is no need to be sad. There are also “exotics” who are unpretentious. The decorative effect of such plants is impressive. Rogersia flowers are a great option from the family of decorative foliage plants.

The external beauty of Rogers is quite impressive. The green and rich appearance is formed by the palmate and feathery leaves. A powerful and strong rhizome is the fundamental basis for the growth of prominent and long petioles of the plant. Rogersia concochestanfolia has the largest and most powerful leaves. The bush has a round shape and fits compactly in any front garden. The pink, white and cream colors attract insects and have a pleasant aroma. The peduncle grows into a panicle up to 150 cm. The inflorescence begins to actively bloom in mid-July and lasts at least 40 days. In autumn, exotic leaves will perfectly decorate the area and acquire a bronze, crimson and purple color. Popular varieties of Rogers The cute exotic Rogersia is a large plant that has been located in the parks of European cities for quite a long time. The American admiral generously borrowed his surname to name this plant. The thing is that a famous military man decided to bring home a picturesque curiosity from China. In the climatic zones of Russia, this find has become widespread and pleases the eyes of many summer residents and gardeners. This garden crop is proudly included in the Saxifraga family. The decorative and monumental nature of this plant attracts the attention of any person. Over time, a modest bunch will grow into a mighty bush, which will consist of vegetative rosettes and a large number of flower stalks. The inflorescences stand out with bright colors (pale white, yellow and pink) and have a delicate aroma. The beautiful picture is complemented by lush green leaves with textured proportions. Rogersia concochestanfolia In order to distinguish Rogers, you need to look closely at the leaves. They can have either a dissected or feathery shape. Rogersia horse chestnut leaves have common features of horse chestnut leaves. This species has shiny leaves, which in turn are divided into seven sinewy leaves. The stems of the plant are strong. The flowers are pink-white with a height of up to 120 cm. At the very peak of inflorescence ripening, the foliage acquires a bronze-green hue. The bush is excellent for planting near gardens and natural reservoirs. It is found en masse in the mountainous regions of China, where the altitude reaches 3000 meters. When the leaf blooms, it acquires a fabulous beet-bronze pigmentation. This is followed by a fresh green color scheme with pronounced veining. The panicles reach 30 cm and are located on strong stems. Flowering lasts for a month. The plant has become widespread in Europe since 1902. Rogersia footform Stop-shaped Rogersia can easily boast of palmately dissected leaves. A peculiarity of this plant is the presence of large denticles along the edges of the petioles. This species begins flowering earlier than its “brothers” (late June) and occupies a large area of ​​land. The distribution area of ​​the culture occupies the territory of North Korea, the high mountain regions of China and Japan. The bush reaches a height limit of 120 cm during flowering. Before this, the figure is about 95 cm. The creeping rhizome forms an integral nutrition system. The palmately dissected leaves have a diameter of 40 cm. The panicles have a rather loose appearance and consist of creamy-white flowers. The period of generative reproduction lasts about 28 days. The Rogersia variety has been widely cultivated since 1870. Rogersia pinnate The feathery shape of the leaves was included in the name of the ornamental plant. The length of the formations can reach 50 cm. And juicy white, cream and pink flowers will colorfully complement the landscape setting in the yard. The bush originates from the Yunnan region. The high mountain forest is a reliable home for the moisture-loving crop. The petioles are large, strong and up to 100 cm long. During the blooming period of the plant, the foliage acquires a purple tint, then tends to a dark green color. The venation is quite noticeable and prominent. The complex panicle consists of fragrant flowers that appear in the first half of July. The most popular garden forms are Alba and Superba. These hybrids are widespread in the formation of haciendas and areas with decorative plantings. Buying Rogers at the moment is not very difficult. Rogersia elderifolia The Rodgersiasambucifolia plant has its origins in Yunnan and Sichuan provinces. The mountainous terrain of this region is famous for its beautiful landscapes. The bush grows at an altitude of 2800-3300 meters in pine forests. During the period of vegetative growth, the height of the representative of the flora reaches 70 cm, and at the time of flowering - 120 cm. The pinnately dissected leaves with a bronze tint firmly resemble elderberry. The fragrant panicles consist of creamy white and small inflorescences. The plant is rarely used in landscape design. In practice, it is even difficult to beg it from professional collectors, because the bush grows very slowly. Features of Rogers One of the key and positive properties of Rogers is its low maintenance requirements. In order to successfully place a plant in a garden plot, you need to carefully study the features of the exotic “guest”. Firstly, the plant feels most comfortable in a dark place with moist soil. Secondly, light and nutritious loams are the most optimal option for the growth of tree-like bushes. The Far East has generously enriched the gardener's summer cottage. The process of acclimatization and long cultivation of the exotic plant was successful. The mountainous regions of China, Korea and Japan stand out for their beauty. The majestic Rogersia grows proudly along the banks of rivers and lakes. Powerful leaves reach a height of 1 m, which gives the plant grandeur and texture. Paniculate inflorescences of white and pink colors fit perfectly into the home garden interior. Rogersia chestnutifolia is widespread. The plant loves moist areas of land that are full of organic matter. The only undesirable places are those that are completely shaded. The formation of a large mass of leaves and large flowering is achieved by selecting an area sheltered from the wind. Moderate watering and proper feeding are the key to normal plant development. Winters with little snow are absolutely not scary for the plant. But spring frosts during the awakening period of the bush can create unexpected troubles. The culture may, if not disappear, then lose its decorative effect and the likelihood of lush flowering. A pond in a private yard can be beautifully decorated with this beautiful plant. A subtle combination of decorative stones and exotic flora allows you to achieve a beautiful effect in the design of space. Planting Rogers and caring for them in open ground is not too difficult for a gardener. Secrets of successful actions: When purchasing a plant, you need to make the final choice on large cuttings. This is explained by the fact that the large version takes root best and acclimatizes easily. Spring frosts can seriously damage even the most powerful and healthy plant. Therefore, it is worth protecting the leaves and buds of inflorescences. Before cold weather, it is recommended to cover the bush with woven material and a natural blanket (leaves, sawdust, etc.). Snow-white winters are often accompanied by severe frosts. Often the buds are damaged and slow down the spring development of the plant. Therefore, after pruning, you need to sprinkle the crop with cow compost or dense woody foliage. Leading agronomists and gardeners have created recommendations for fertilizing. This process will significantly affect the quality development of the entire bush. The action takes place in May or July. For this purpose, complex fertilizers and a diluted solution of an organic mixture are used. Planting, care, feeding and propagation of Rogers The key principle when planting a plant is the rational application of humus, compost or peat formations. In this case, the plant will definitely respond to your care and delight you with a beautiful inflorescence. The root system goes deep into the ground up to 6 cm. And the exotic bush reaches large sizes within 3 years after planting. The unique property of Rogers is based on the absence of the need for replanting for up to 10 years. First of all, you will need to dig a deep hole and place a mixture of leaf humus and manure there. Sand and brick chips are used as drainage. Removal from the pot occurs after thorough watering so that the root system is in an earthen coma. The rhizome is placed in a hole in the ground and compacted tightly. To retain moisture in the soil, mulching (sunflower husks, straw or chopped bark) is required. The period of active plant growth requires systematic watering. In the final autumn period, the bush is pruned at the root. This allows the plant to “fall asleep” and decorate the garden next year. The bush is winter-hardy and can withstand frosts down to -25°C and does not require additional shelter. Although a light cover of leaves won't hurt at all. Rogersia is rarely susceptible to disease, this is explained by the fact that it contains antiseptic substances. There should be good drainage under the rhizome. Otherwise, the process of rotting will begin. The big enemies of such a planting are grape snails and ill-fated slugs. Often there is a rust fungus on the leaves of the bush. Damaged areas should be removed and treated with an effective fungicide. The chemical treatment process is carried out in the warm season and in the first half of the day. In this case, the leaves of the plant must be dry. Rogersia and its care are quite simple. Loss of leaves and flowers will indicate improper care. The main cause of death is a radical lack of moisture. Strong winds and dangerous rays of the sun can cause brown spots to appear. An effective measure to save a culture is transplantation. Organic and mineral nutrition is an excellent addition for exotic Rogers. The integrated application of copper, zinc, sulfur, molybdenum, potassium, nitrogen, and magnesium allows to activate growth and maximize the growing season. This event is especially necessary during the growth and development phase of a young bush. The plant reproduces quite easily. In the spring, knowledgeable gardeners divide the rhizome into several parts and plant it in a pre-prepared area. The second half of summer allows you to propagate Rogers from leaf cuttings. The least effective option is the method of propagation through sowing seeds in the ground. In this case, seedlings develop slowly. Rogersia often cross-pollinates with each other. Therefore, to collect high-quality seeds, you will need to plant the plants at a good distance from one another. The sowing process is long and painstaking work. The most important problem of this activity is the low germination of seeds. Hybrids often revert to the maternal form and gradually degenerate. The first stage of such propagation is equipping a small container with a moist substrate. The box should be kept indoors (T = 0°C) for several weeks. Then the regime increases to 15°C. When forming the first shoots, it is very important to control the humidity level. After the seedlings reach a height of 15 cm, they are transplanted into a large container. The final move to the garden bed takes place in the fall. Sooner or later the need arises to divide the bush. The most favorable period for this is autumn. The thing is that the root system is divided into pieces (up to 10 cm). These parts are moved to a special box with a planting depth of 5-7 cm. Moistening the soil is mandatory. Storage lasts up to 4 months at temperatures from 5 to 10ºС. As the bush germinates, the plant is transplanted into a pot of peat mixture. Advantageous neighborhood of Rogers Forming plant compositions is a real art. People study this profession for more than one year. Rogersia subtly combines the effect of youth and freshness. In alliance with other plants, the culture forms the most beautiful combinations in the front garden. Fern, bergenia, bell. All these representatives of the flora look spectacular in flower beds and under the canopy of garden trees. Tall plants (lungwort, periwinkle and mountain weed) are no exception for an advantageous proximity to a tree-like bush. For example, the presence of buzulnik will emphasize the proper placement of an exotic perennial and will form a long-term and reliable tandem. If you are the owner of a small apiary, then you probably have mint growing nearby. The friendship between Rogers and this plant is quite reliable. After all, the aroma that these crops will emit will not leave inquisitive bees indifferent. An experienced beekeeper knows that such a smell pacifies pollinators and brings harmony to the work of fanatical workers. Ultimately, the aesthetic takes on a more colorful direction. Shade-tolerant shrubs are an excellent option for cohabitation with Rogers (astilbe, hosta, forest geranium, purple foxglove, broadleaf bell). Coniferous shrubs (yew, rhododendron) are also reliable neighbors. Application in landscape design Large decorative leaves, which have a bright color, make the plant quite exotic and memorable. The inflorescence is 30-40 cm long and has a racemose shape. This gives the culture a spectacular look and additional entertainment. Rogersia is suitable for flower beds and prefers to occupy a place directly in the shade. The representative of Saxifraga forms magnificent compositions of the tree family, forms the edging of the front garden, the border and the banks of artificial reservoirs. The ability to grow in dark places is the main feature of the Far Eastern plant. Therefore, an alliance with fragrant juniper, tall thuja, mysterious spruce and healing mahonia will be very strong. When creating a design project, you need to keep in mind that a grown bush will cover neighboring flowers and crops with powerful leaves. The most striking combination will be the placement of narcissistic daffodils and bright toffees in the garden bed. And the rich color range starts from a reddish-purple hue (burgundy) and ends with a bronze iridescence of the leaves. Most designers use Rogersia in designing stone gardens. The secret of success in creating a quality combination lies in both good taste and the ability to contemplate the beauty of nature. After all, even competent planting on an ordinary lawn can create a fabulously beautiful corner. Photo of Rogers in the creation of landscape design

The genus Rogersia includes 8 perennial, ornamental deciduous, rhizomatous species growing in the mountainous areas of China and Japan.

All of them are distinguished by large, palmate-lobed or palmately divided foliage and large-sized paniculate inflorescences made up of white flowers. Rogersia is a tall, wide and chic exotic plant that attracts special attention.

Varieties and types

It is the most common species, the essence of the name of which lies in its similarity with the foliage of the tree of the same name. This species is characterized by pink flowering and the fact that it grows best along the banks of water bodies.

- like all other Rogers, it grows in natural conditions at a very high altitude - up to 2.9 km above sea level. This plant reaches a height of 140 cm, while the diameter of the leaves can reach up to 50 cm. During blooming, the foliage has a beautiful beet-bronze color, which is later replaced by an equally attractive fresh green with relief venation.

The flowers are small, but when collected, they form pinkish-white fragrant inflorescences up to 30 cm long, rising above the foliage. The flowering of the species begins at the end of June and ends at the end of July. The shoots and leaf petioles have brownish pubescence.

• Subspecies Rogersia Henrici features sun resistance. In spring, its leaves are coffee-milky in color, and in summer they are bright green.

In the mountain pine forests of China it “climbs” even higher - 3-3.9 km, and itself somewhat lower - up to 1.2 meters in height. Large pinnately divided foliage, blooming, turns purple, then turns dark green, also with raised veins. The panicles of inflorescences are from 25 to 30 cm long, either white or pink, and emit a pleasant aroma during flowering (about 25 days) in July.

• Famous garden form Rogersia elegans - characterized by pink flowers,

• and in the variety Rogersia chocolate wings they change throughout the development season - from pink to a reddish hue, and the foliage can boast of the same, which changes from chocolate tones to multi-colored ones with green and red inclusions and, in the fall, returns to chocolate again.

• Variety Rogers Bronze Peacock stretches in height above the main species - up to 1.5 meters, its leaves change color from pinkish-purple to bronze-green, and the flowers are cream.

Rogersia podophylla (stopolia)

It grows in Korea, China and Japan, and is characterized by a pinnate height similar to Rogersia and palmately dissected relief leaves up to 40 cm in diameter.

The color of the leaves during blooming is bronze, then a less saturated green. The creamy white flowers are arranged in numerous panicles that bloom for about a month, starting in mid-June.

• For variety Rogersia Braunlaub Characteristic is the reddish-brownish color of the foliage.

It has been bred into a separate genus, which contains only one rare species in floriculture - astilboides lamellar. Its natural habitat is located in the territories of Northeast China and Korea, on the edges of forests and ravines.

The differences between Astilboides lamellar and Rogersia of various types are quite impressive - it is not tall (up to 30 cm in height), has hard, elastic and truly huge leaves with a diameter of up to 70 cm with long, strong petioles. The elongation is also characteristic of the peduncle - it reaches 1.5 meters in height.

The inflorescences differ less noticeably; they consist of small, cream-colored flowers that droop at the end of flowering, reaching a length of 25 cm. The flowering period begins in July and lasts about a month.

Rogersia planting and care in open ground

Success in growing Rogersia largely depends on choosing a suitable site for it. This is semi-shaded, which does not allow the plant to remain in the open sun all the time.

It is highly not recommended to plant several varieties of this plant in close proximity to each other, as mutual pollination will occur with the subsequent loss of individual qualities. The planting site should also provide protection from the wind during cold weather.

Astilbe is also a representative of perennials of the Saxifraga family. You can find many recommendations for growing when planting and caring in open ground in this article.

Watering Rogers

In fact, further care of Rogers is relatively simple and mainly involves regular and abundant watering. It’s even better if the plant is placed near a pond, where moist air will give extraordinary brightness to the foliage.

Watering is especially important in hot summers and when there is a lack of natural precipitation, and in the case of a location close to a permanent source of water, they are carried out only after first checking the soil - if it is wet, it is not worth watering.

Loamy, nutritious soil is well suited for normal development. Rogersia likes humus, compost and peat, and it is the mixture of these components that is optimal.

The soil within the growing radius must be systematically loosened, simultaneously removing weeds - this way, among other things, the soil will be saturated with air, which is important, and excessive evaporation of moisture from the soil can be prevented by mulching the tree trunk circle with bark or peat. Mulch is sometimes added after the loosening procedure.

Rogersia transplant

Rogersia will delight the eye for decades, without requiring replanting, if the place where it grows is chosen correctly! At the same time, she tolerates the transplant perfectly. Rare cases of root rot have been reported in Rogers plants planted in swampy lowlands.

Replanting it to a drier area will help to cope with this problem, although you can dig up a bush, arrange drainage in the resulting hole from fragments of thick branches, expanded clay, and fragments of pottery and replant it.

Rogersia feeding

Feeding takes a lot of time during the entire growing season, especially during active growth and flowering.

The plant lives well with both mineral and organic fertilizers, and it is best if the fertilizing is complex organomineral - with all the microelements Rogers needs.

Great emphasis should be placed on the presence of nitrogen, potassium and phosphorus in the soil and combine fertilization with irrigation.

Rogersia pruning

Sanitary pruning of Rogers includes removing broken and dried branches, tearing off diseased leaves, and plucking flower stalks when flowering ends.

Before the arrival of cold weather, you must tear off all the leaves of the plant and cut off all the stems almost to the root - this will make it easier for it in winter.

Rogersia preparing for winter

Although Rogersia is not a plant very susceptible to frost, it is still recommended to organize a shelter for it from fallen leaves for the winter.

Under a layer of snow (especially thick) it generally feels quite comfortable, but caution should be exercised in early spring, when there is no snow, but frosts are still strong. This is when it is necessary to provide additional cover, for example, based on non-woven fabric.

Rogersia reproduction

Any type of Rogersia can be propagated by seed and vegetative methods. The first is considered ineffective due to the extreme slowness of seed germination at home.

Moreover, the young specimen will begin to bloom no earlier than the 4th year.

Propagation of Rogersia by cuttings

The second method, based on cuttings, does not have these disadvantages. It involves preparing cuttings in mid-summer from leaves with a heel, then moving them into a germination stimulator and burying them in the soil mixture for rooting.

The whole process ends with the appearance of strong roots and further planting of the plant in open ground. The optimal time for planting, allowing Rogers to get stronger before the arrival of winter, is the beginning of spring.

The landing itself should be taken into account several features described below:

• The soil for planting must be free of weeds and turf and dug to a depth of 30 cm;
• The soil should be flavored with humus, peat and mixed with deciduous and forest soils;
• The dimensions of the dug planting holes should slightly exceed the dimensions of the root system;
• At the bottom of each planting hole, it is necessary to lay out a drainage layer consisting of small stones, crushed bricks or gravel;
• Before planting a seedling, it must be watered;
• The planted plant should also be watered in the planting circle area, then the soil should be mulched with tree bark or peat.

Diseases and pests

The unique antiseptic properties of Rogers allow it to easily repel the attacks of insect pests and not get sick. May rarely occur root damage by slugs And foliage rot .

Infected areas are removed, then the plant is treated with a fungicide during the day. To prevent these diseases, you just need to not overdo it when watering.

If the soil is oversaturated with nitrogen, this may have a positive effect on foliage growth, but a negative effect on flowering. Rogersia may not bloom in 2 more cases - with irregular and weak watering and exposure to bright sun.

Rogersia is a perennial ornamental deciduous shrub of the Saxifraga family. The evergreen plant forms a powerful shrub thanks to its embossed long-petioled leaves. The root system of the plant is a modified stem, which is located horizontally underground, which facilitates the procedure of propagation and planting. In this article we will tell you how to plant and care for Rogers in open ground and give advice to gardeners.

Rogersia naturally blooms with white flowers with a cream tint. Garden varieties have flowers in yellow, pink, cream and white. The shrub reaches a height of up to 1.5 meters.

Rogersia grows well in the climatic conditions of central Russia.

Optimal conditions for growing Rogersia in the garden

Rogersia successfully takes root in shaded garden areas, which allows gardeners to turn a shaded area into a beautiful flower garden. Rogersia has the ability to accumulate light, so the shrub has enough sunlight penetrating throughout the daylight hours through the foliage of other plantings.

Rogersia needs about 3 hours of sparse sunlight in the middle of the day.

The Rogersia root system is distinguished by the fact that it grows quite quickly and forms root stems with buds, from which daughter plants are formed. It is for this reason that Rogersia is best planted in a large, spacious area. Rogersia is not recommended to be planted next to plants with a weak root system, since the rhizome of the shrub can “strangle” such plants as it grows.

Rogersia should not be planted in low-lying areas and areas with close groundwater. Although Rogersia is a moisture-loving plant, it does not tolerate soils with any amount of water accumulation.

The soil for planting Rogersia should be loose, fertile, and well-drained.

Tip #1. Rogersia is a shade-loving and moisture-loving plant, so it does not grow well in dry shade. The shrub will not be afraid of dry shade if the soil is generously covered with mulch in early spring. Such soil will always be warm and saturated with the optimal amount of moisture.

Preparing the soil for planting Rogersia

As a mineral fertilizer, you should choose complex fertilizers, which should include not only nitrogen-potassium-phosphorus substances, but also microelements:

• iron;
• magnesium;
• zinc;
• copper;
• sulfur;

Mineral fertilizers are applied to the soil throughout the entire growing season. In the table we consider universal mineral fertilizers containing microelements, as well as their application rate for decorative deciduous plants.

Step-by-step instructions for growing Rogersia seeds

Rogersias are rarely propagated by seeds. This method does not always allow preserving the genetic material of the mother plant. There are problems with seed germination. Seedlings are characterized by long growth and development. Seeds are sown in planting containers in the fall - late September - early October. Let's look at step-by-step instructions for growing Rogersia from seeds:

1. Whole seeds without defects are selected for sowing. Selected seeds are soaked for 5-10 minutes in a weak solution of potassium permanganate. Before sowing, the seeds are mixed with clean sand.
2. Planting containers are disinfected with a solution of potassium permanganate. Form 5-6 holes at the bottom of the container.
3. The soil mixture for sowing should be fertile, loose and light. Such a soil substrate will provide good access to oxygen, and will also ensure uniform moistening of the entire volume of the substrate in the planting containers. The soil mixture should include components such as turf soil, sand, peat and wood ash. Turf soil, sand and peat in a ratio of 1:1:1. Wood ash is added to the soil at the rate of 10 g of ash per 1 kg of soil mixture.
4. The planting container is filled with the prepared substrate and watered moderately with warm water. The seeds are mixed with sand and sown in planting containers. The sowing is covered with film. Place planting containers with sowing on the site for freezing.
5. In early spring, containers are moved to the windowsill. Since the seeds germinate poorly and very slowly, seedlings will appear no earlier than 30-35 days.
6. Seedlings dive into smaller containers. As soon as the seedlings get stronger, they are transplanted into a garden bed in open ground.

Tip #2. For those who practice propagation of Rogersia from seeds, it is not recommended to plant several varieties in one area. Such planting can lead to cross-pollination of plants. Seeds obtained from cross-pollinated plants may contain genetic traits that were acquired during cross-pollination from another related variety.

Propagation of Rogersia by cuttings of rhizomes

The optimal period for the propagation of Rogersia is spring and autumn. Rhizome segments are formed in the fall. The horizontal root of the mother plant is dug up and divided into segments 8-10 cm long. The segments are planted in planting containers with fertile soil substrate. The substrate must include the following components:

• Fertile and loose garden soil;
• Sand;
• Peat.

The above components are mixed in equal quantities. Pre-treated sections of rhizomes in a growth stimulator are planted in the prepared soil mixture. The planting container is moved to a cold room for the winter until spring. In spring, containers are moved to a warmer place. As soon as the seedlings appear, they are transplanted into peat pots. At the end of May or beginning of June they are planted in a permanent place in open ground.

Using Rogersia in landscape design

Rogersia, due to its decorative leaves, goes well with many ornamental and flowering plants. Rogersia is used in landscape design to create picturesque compositions.

The exotic plant is planted in a flower bed, in mixborders and along rocky paths. Rogersia looks good at the foot of artificial reservoirs and ponds. The shrub looks interesting in rockeries. It is not recommended to use Rogersia in alpine slides due to the height of this plant.

Rogersia looks beautiful among the colorful flowering plants. The picture shows a diagram of a flower arrangement in which Rogersia will look most harmonious.

Experienced flower growers claim that Rogersia does not go well with all plants. Only those plants with which Rogersia can create a single horizontal surface are suitable as companions. In the table we consider the types of plants with which Rogersia looks organically:

The best varieties of Rogersia

In nature, there are approximately 8-9 species of Rogersia; cultivated – 3 species. Let's consider the types and varieties of Rogersia that are suitable for planting in the garden:

Rogersias can withstand temperatures down to -25 °C and do not require shelter

Care plan for Rogersia outdoors

• Spring. The old mulch is removed, the soil is loosened, fed and covered with a new layer of mulch. In spring, feed the plant with organic fertilizers. After feeding, the plant is covered with non-woven material to protect it from morning frosts and return frosts. During active growth of the above-ground part, the plant is watered abundantly.
• Summer. The plant is fed with universal mineral fertilizers for decorative deciduous plants. Conduct a visual inspection and, if exposed roots are found, sprinkle with soil. Water abundantly, but not often. As soon as the plant fades, cut off the flower stalks and remove dry leaves.
• Autumn. Remove leaves and cut off all shoots. Mulch again with dry leaves or humus. Read also the article: → "".

Serious mistakes gardeners make when growing Rogersia in open ground

1. Rogersia is grown in low-lying areas and areas with close groundwater.
2. Rogersia is planted in the sunniest areas.
3. For the winter, the plant is left with leaves and shoots.

Frequently asked questions about growing Rogersia

Question No. 1. How many days does Rogersia bloom?

Rogersias bloom for about 1 to 1.5 months, after which active leaf growth begins.

Question No. 2. How to protect Rogersia from frost and snowless winter?

For the leaves and rudiments of Rogersia inflorescences, the main enemy is return frosts. To protect the bush from early spring and return frosts, it is necessary to cover it with non-woven material. The plant will survive a snowless winter well if in the fall, after cutting the leaves, the plant is sprinkled with compost or fallen leaves of fruit trees. A small layer of compost or foliage will protect the plant's regeneration buds from frost.

Question No. 3. How many days passes from sowing to Rogersia flowering?

Seedlings begin to bloom at 3-4 years.

Question No. 4. How many years can Rogersia grow in one place?

Rogersia has been growing in one place for more than 8 years. With proper care of the plant – more than 10 years.

Rogersia is an exquisite and beautiful plant, named after John Rogers, an admiral and head of an expedition heading to China. There, in the 1850s, Americans first encountered an unusual plant and described it in 1885, giving it the name Rodgersia. Rogersia has been known in Russia since 1878.

Taxonomy

Rogersia belongs to the class of dicotyledonous plants, which are classified as angiosperms, or flowering plants. The family to which Rogersia belongs is called Saxifragaceae; the number of species in the family does not exceed 600. Life forms are represented exclusively by herbaceous plants. The genus Rogersia is one of the smallest in the family - it contains eight species.

Photo: Rodgersia aesculifolia.

Area and place in biocenoses

The homeland of Rogers is Southeast Asia, the territory of Japan, Korea and China. It prefers to grow in shady areas or areas that receive sun in the early morning or evening. Rogersia is found in damp forests, along the banks of streams, in forest edges and clearings. It grows in the mountains, sometimes at an altitude exceeding 3200 m. The peculiarities of growth must be taken into account when planting and caring for Rogers.

Morphology

It is a herbaceous perennial with a taproot system, which is especially pronounced in young plants. An adult Rogersia develops an underground rhizome from which additional roots emerge. The rhizome is a modified stem, not a type of root. The main difference between the modified shoot is that buds form on it. Due to the presence of a horizontally located rhizome, planting and propagation of Rogers is very easy.
Rogersia leaves are simple, palmate or pinnate, large in size, sometimes reaching 1.5 meters. Some sources contain evidence that Rogersia has complex leaves. This botanical error arose as a result of the fact that some plant species, such as Rogersia concochestanifolia, are palmately dissected. Therefore, simple leaves, thanks to deep cuts, look like complex ones. It is easy to verify that Rogersia has simple leaves in the fall: its entire leaf withers. In plants with compound leaves, during leaf fall, each leaf is torn from the petiole.
The leaves of different types of Rogers have different degrees of dissection of the leaf blade: lobed, divided and dissected.
The small flowers are collected in inflorescences, the plant is entomophilous, pollinated exclusively by insects and is a good honey plant.
In nature, Rogersia flowers are white, but in garden varieties and hybrids you can find cream, yellowish and pink shades. Dry fruit - capsule.

Growing conditions

Lighting
The best option for planting Rogers is partial shade or places with bright diffused light without direct sunlight. Rogersia can withstand morning sun that is not too hot and can grow in the shade. A good option for planting Rogers is the proximity of other plants; in addition to the aesthetic component, plants in a group better retain moist air .

Soil and fertilizers
Rogersia prefers substrates rich in humus, with the addition of leaf humus or forest soil with particles of not completely decomposed leaves. The substrate should be moist, but without stagnant water, loose and aerated. The rhizomes of the plant are close to the surface, so when caring for Rogers, you need to make sure that they are not exposed. If this happens, then you need to cover them with humus or soil to avoid drying out.
Mineral and organic fertilizing is a necessary element when planting and caring for Rogers. Complex fertilizers must contain not only the main components: nitrogen, potassium and phosphorus. The plant also needs trace elements: iron, magnesium, molybdenum, zinc, copper, boron and sulfur.
Organic fertilizing can be applied throughout the growing season, but is preferable in spring and summer, during the period of Rogers growth and flowering.

Watering and moistening
Rogersia prefers moist air, just like in its natural habitats. Therefore, planting Rogers should take into account its love for moisture; dry places are not for this plant. Rogersia can grow in very damp places, near fences, next to the walls of houses, but not in lowlands where moisture accumulates after rains. Stagnation of water leads to disease and rotting of roots.

Care

Dried, yellow or damaged leaves of the plant should be removed. After flowering, if it is not planned to collect seeds, the flower stalks are also removed.
In autumn, Rogers care involves removing all leaves and non-viable shoots; application of mineral fertilizers; covering with leaves, compost or sawdust from deciduous trees.
Rogersia is a frost-resistant plant, but it needs to be covered because it can suffer from early frosts or in winters with little snow. In the spring, during possible frosts, Rogers are protected with spunbond (non-woven covering material of the Lutrasil type).

Planting and propagation

Rogersia is planted in spring or autumn by dividing the bush. Rogers is planted in soil that is enriched with organic matter. The advantage of autumn replanting is that after overwintering, Rogers will vegetate more actively in the spring.
Rogersia is propagated by dividing rhizomes in the fall. With this method of propagation, it is best to plant parts of the rhizome first in flat trays with soil. The room temperature should be 5-10 degrees, the soil should be slightly moist. In spring, grown plants are transplanted outside.
When propagating Rogers by seeds, one must take into account: the frequent return of hybrids to maternal forms; possibility of cross-pollination of varieties; problems with seed germination; long period of growth.
The seeds are pre-sown in containers with a moist substrate rich in organic matter, and left at a temperature close to 0. After several weeks, the temperature is raised to 10-15 degrees. After germination, seedlings need moist air and frequent fertilizing with dissolved fertilizers.
After Rogers sprouts reach 10-15 cm in height, they are transplanted into separate small containers. These containers can be kept outside in spring and summer, and Rogers can be planted in open ground in the fall. When planting Rogers in containers, the death of seedlings can be avoided, since in a greenhouse the care of Rogers is more thorough.

Diseases and pests

Rogersia, thanks to the antiseptic substances contained in its composition, is practically not susceptible to disease, but with poor soil drainage it is damaged by rot. Among the pests it is eaten by slugs and grape snails. Occasionally, leaves are affected by rust fungus. In this case, you need to remove them and treat the above-ground parts of the plant with a fungicide several times. It needs to be processed in the warm part of the day, when the evening is still far away; the Rogers leaves should be dry.

Use in landscape design

Rogersia has very beautiful large decorative leaves, which in some varieties are painted in bright colors, which makes the plant even more attractive. Rogersia flowers are very small, but the inflorescences are large, 30-40 cm, racemose or drooping, very showy and unique. Rogersia is both an ornamental-leaved and an ornamental-flowering plant. It is suitable for flower beds located in shade or partial shade; compositions consisting of woody representatives of the plant kingdom; edging flower beds and paths, like a border plant; decoration of the banks of artificial reservoirs.
An important advantage of Rogers is its ability to grow in shady, damp places. It goes well with other shade-tolerant plants: ferns, hosta, periwinkle, bergenia. The composition of different types and varieties of Rogersia, which will differ not only in the shape of the leaves, but also in their color, looks interesting.
Rogersia looks impressive together with small shrubs, dwarf or creeping forms of coniferous and deciduous trees: juniper; thuja; prickly spruce; Mahonia.
When planting Rogers, you must not forget about its large size and take into account the fact that it can obscure smaller plants in the flowerbed. Rogersia goes well with irises, daffodils, and blueberries that bloom in early spring.
Rogers leaves have another decorative feature; they change color several times during the season. In the spring, at the beginning of the growing season, the young leaves are reddish-purple or bronze. In late spring and summer, the leaves are various shades of green, and in the fall the leaves turn burgundy, red or purple again.

Types of Rogersia

Rodgersia podophylla. The height of the bush is 100 cm, the height of the peduncle reaches 1.5 m. The leaves are embossed, in spring and autumn with a bronze tint. In cultivation since 1870, the hybrids have inflorescences in various shades of white and cream.

Rodgersia aesculifolia. The height of the bush is 80-100 cm, peduncles - 1.2-1.4 m. Homeland - mountains of China. The leaves resemble chestnut ones, up to 50 cm in diameter, with a bronze tint at the beginning of the growing season. Inflorescences are white or pinkish.

Rogersia aesculifolia var. henrici . A subspecies of horse-chestnut-leaved Rogersia, sometimes separated into a separate species, Rodgersia henrici - has the most luscious color of green leaves, reddish in autumn. Inflorescences of various shades of cream and pink. Tolerates a sunny location well.

Rogersia pinnata - height of the bush is up to 60 cm, peduncle - 120 cm. The leaves resemble rowan, when young they are orange-cinnamon in color. Pink flowers are collected in panicles up to 30 cm. In spring it begins to vegetate later than other species. Blooms in July. Has many varieties and hybrids.

Rodgersia sambucifolia - belongs to the compact Rogersia and resembles the cirrus. Native to the mountain forests of China. The height of the inflorescence is 120 cm, the height of the bush is 70 cm. In a sunny location, its green leaves with deep veins acquire a bronze tint. Blooms in July. The small inflorescences are very fragrant.

It is not often that you can find this interesting plant in our gardens - Rogersia, although it has been familiar since the nineteenth century, when it was brought to our country from. This miracle of nature is named after the man who led the expedition to the Middle Kingdom - John Rogers.

This perennial plant grows significantly in width in a couple of years, and therefore initially requires a large area for planting. Beautiful brown-burgundy or emerald leaves, for which Rogersia is valued in the garden and has a rather large diameter. But the flowers of the plant, on the contrary, are small, collected in paniculate inflorescences and you can admire them for about a month from May to June.

Types and varieties of Rogers

Today, our flower growers cultivate the four most popular types of Rogers:

• elderflower is a rather rare species that, unlike its relatives, blooms in mid-summer; small white flowers of unusual shape exude a pleasant aroma;
• lamellar - a very unusual type of Rogers, the leaves of which resemble huge dishes, and the variety itself is completely unpretentious in care;
• pinnate - an original variety of Rogers with small pink flowers located on a high peduncle;
• chestnut-leaved - the most common species, which received its name for its similarity with the leaves of the tree of the same name; like Rogersia pinnate, it blooms pink and prefers to grow on the banks of natural and artificial reservoirs.

Landing place

For Rogers to show its full splendor, you will have to think carefully about the place for it. After all, this plant does not really like the sun, but in partial shade it grows just fine, pleasing the eye with its unusual shades of foliage.

The soil for the plant is loamy, but quite nutritious. In addition, the area where the plant is planned to be planted must be well protected from winds during the cold season.

The plant is very responsive to watering, but it is even better when the plantings are located around bodies of water, because then the air saturated with moisture has the most positive effect on the brightness of the leaves.

Rogers care

This plant can be safely classified as simple and problem-free. If you plant Rogers in open ground, then caring for it comes down to regular and abundant watering, without which the plant does not develop. Given the right location, this ornamental plant lives without replanting for up to 10 years.

In addition to abundant watering during the summer season, the gardener will only have to remove dried leaves and flower stalks when they have bloomed. Due to the fact that Rogers is practically not affected by pests, you can forget about treating this corner of the garden or flower garden with fungicides. Most often, Rogersia tolerates winter well under a large layer of snow. But if it has not fallen yet, and frost is just around the corner, then you should cover the plants with leaves or spruce branches. In the northern regions, where there is a threat of freezing, it is best to place the rhizomes in the basement in the fall in containers with sawdust or soil, as we are used to doing with.

Reproduction

Rogers are replanted throughout the summer season, although the new plant takes root best in the spring. To propagate a bush, you should dig out the necessary part of the rhizome with a shovel, carefully cutting it. Rogersia is rarely propagated by seed, since this process is very lengthy and labor-intensive.

Why doesn't Rogersia bloom?

And although all the beauty of the plant lies in the foliage, and not the flowers, many inexperienced gardeners are bothered by the lack of flowering. This can happen when the plant lacks something or has an excess. This can only be found out experimentally by observing the bush.

It happens that the soil is too saturated with nitrogen, and therefore the foliage grows simply gigantic, but to the detriment of flowering. Or, initially, since spring there was irregular and insufficient watering, and Rogers was unable to set buds. If the place for the plant is chosen poorly - in bright sun or in a lowland where the roots get wet, then you may not see flowers.
