Rogersia - herbaceous perennial, originally from China. Habitat at home - mountainous areas, where it grows on the wet, shady banks of rivers and lakes. The plant was brought to our country in the 50s of the last century, and during this time it was able to win the place of the honorable "Tenelyub" in gardens and front gardens.
Description and features of Rogers
Shy Rogers - shade-tolerant plant, large-leaf perennial with an interesting shape and texture of the leaf. The plant looks great in mono plantings and in combination with many other perennials. In flower beds, you can set off large leaves of rogers, planting low blue irises, majestic fans of ferns, or weightless ears of fox tail next to it.
Different types of Rogers are perfectly combined with white or pink-horticulture bushes, as well as with an euonymus or a gift. Rogers' partners in the flowerbed, with their diversity and unusualness, complement and shade the powerful foliage of its bush. Rogers' leaves have a special decorative effect, but its paniculate, light and delicate inflorescences-panicles are not without charm. The flowers of this plant have a pleasant delicate aroma that can be enjoyed for a month. The joint plantings of Rogers and spring early-flowering plants, for example, primroses of periwinkles and tiarell, also look beautiful. Rogersia perfectly adorns the garden, thanks to which gardeners grow a variety of varieties and types of this plant.
They differ from each other in leaf shape, color and leaf structure:
(Rodgersia sambucifolia), Rogersia Elderberry - The name is dictated by the fact that the structure of the leaves of this species is similar to the structure of elderberry leaves. The bush is quite high, and often reaches 1.4 meters. Stems burgundy plants, green leaves. The plant has beautiful pink flowers that bloom in June and continue flowering for more than a month.
(Rodgersia pinnata), Rogersia Feather - The leaves of this species are elongated and elongated. Bushes are low, not higher than 50-60 cm. The structure of the leaf has a clear similarity with the rowan leaf. The flowers are small, inflorescences paniculata, elongated shape, cream color.

Choosing a place for landing Rogers
Rogers is not only a shade-tolerant, but also very shade-loving plant. Direct sunlight inhibits it, so it easily tolerates only the morning sun for a half to two hours. Of course, the place for landing Rogers need to be chosen according to these requirements. You can arrange a capricious in the penumbra or under a tall tree, the crown of which will pass the scattered sunlight.
Rogersia lives well in the garden in mixed plantings with other pischnolistymi plants, preferably with different height of the bushes. Under such conditions, a microclimate is formed and the humidity of the soil and air lasts longer.
Different types of Rogers are close relatives and, when planted next to several varieties, may pereopylitsya, losing a significant part of their decorative effect. In order not to be too cold-resistant, the plant does not freeze over in early spring, for planting it is necessary to choose the places where the snow heaps melt last. Usually, these areas are located in the shaded corners of the site, and are ideal for Rogers.
Planting and breeding Rogers
When choosing a place for planting, you need to take into account all that is known about Rogers. For example, it is no secret that she prefers moist soils, which can be located near the northern wall of a house or in a shaded place near the fence, in a shade where it is always dark, damp and no plants want to grow. Here, with pleasure, Rogersia will spread his lush leaves.
When planting, it is still necessary to avoid openly swamped areas, since stagnant moisture in the soil leads to the rotting of the root system of the plant and its death. Rogersia quickly soaks up, so its cultivation is impossible in places with stagnant groundwater.
The shrubs are planted at a considerable distance from each other and from neighboring plants, since the rogers will subsequently grow magnificently upwards and to the side, and at close proximity will simply drown out their neighbors.
Division of rhizomes
How to plant rogersija spring? Very simply, in May the plant can be planted just by dividing the bush. When an adult wintered plant has already grown ground stalks (up to 5–15 cm high), the bush can be divided by cutting it with a sharp shovel in half or into three parts. The main part of the bush is not disturbed, but simply digged out the cut-off parts of the bush and seated. Reproduction of Rogers by dividing the bush has a positive effect on the plant, because a bush that has grown too much oppresses itself: it lacks light, moisture and nutrition. Therefore, the size of the bushes must be periodically adjusted by digging.
When planting a new Rogersky bush, you must:
- dig up a landing hole before splitting a bush;
- put a humus spade into it, pour in phosphorus-potassium fertilizers, or pour out the ammophos match box (the fertilizers are mixed with the soil at the bottom of the planting pit).
- pour a bucket of water into the landing pit;
- dig out a part of the divided Rogers bush and plant on a prepared place;
- The planted bush is watered from above and waited for the water to be absorbed, after which the soil under the bush can be mulched with humus or peat moss.
Autumn reproduction of Rogers occurs in late September and early October. To divide the rhizomes of the bush, the entire ground part of the plant is pre-cut. Rhizomes are excavated, divided, dipped in a pink solution of potassium permanganate for disinfection from fungal diseases, dried in the sun and planted in a new place. Planting pits, as well as during spring planting, it is recommended to fill with organic matter.
The rhizomes dug out in the fall and prepared for planting can be safely stored in the basement until spring (provided the room temperature is above zero). For this, the rhizomes are laid out in boxes with slightly moistened sand, after which the rhizome several times during the winter and the sand in which they are stored are sprinkled with water. In early May, rhizomes with already sprouted stems are planted in a permanent place. And here in the garden is already growing rogers, and both its planting and further care in the open field will not take much power from you.
Did you know? Rogersia bush can grow in one place for ten years.
Growing from seed
When gardeners propagate Rogers seeds, it often turns out that quite a result is not what they were trying to grow. What is the reason? It is possible that different types of Rogers pereylis among themselves or you used the seeds of hybrid plants (they are more effective than varietal). Seeds collected from hybrids, with further cultivation can be split into parent forms.
Nevertheless, it is quite possible to grow an adult Rogers bush from seeds. For this:
- Seeds are sown in winter in a container with soil well-filled with organic matter. Seeds are sown to a depth of 1 cm, after which the containers remain to overwinter in a cold, dry room. In February, tanks with sown seeds are brought into a warm room. Seeds that have passed in the cold stratification germinate much better. When sprouts seem, the capacity with seedlings is rearranged on the window.
- Further care is to timely watering and loosening the soil. When the Rogers seedlings reach a height of 15-17 cm, they dive, seated in separate pots.
- In the stage of six true leaves, young seedlings need to be fed with a complete complex fertilizer (fertilizers suitable for azaleas). Ready-to-use fertilizer bags can be purchased at garden stores.
- At the onset of stable positive temperatures, pots with Rogers are put out into penumbra, where it will grow until autumn. In the fall, grown plants are planted in the ground at a permanent place.
Did you know? In winter, young plantings harbor much more carefully than old bushes.
How to care for Rogers
Care of rojercia is the timely removal of dried or damaged leaves, as they significantly reduce the decorative plants. When rogersia blooms, the testes that form are cut out. If the seeds of this plant are needed, then one or two seed plants are left on the bush until the seeds are fully ripe. It is advisable that the seed plants, which are unappealing in appearance, should not be left in the foreground of the flower bed.
In the summer, it is necessary to ensure timely watering of the Rogers root, as well as timely root or foliar (per leaf) dressing. Autumn care for rojersia consists in removing the stems and fading leaves, fertilizing the soil under the bushes, and covering the soil in the bite area for the winter with cover materials. In spring, sprouts that appear should be protected from night frosts, covering them with non-woven materials.
Watering mode
The plant is very demanding for watering. In summer, hot months, Rogers should be watered at least twice a week. Given the rain or excessively wet summer, the irrigation schedule can be adjusted. Rogers is not afraid of watering with cold water, so it can be watered directly from a hose.
With the arrival of autumn, but before the first frosts, until the works on plant shelter for the winter were carried out, the main autumn water-supplying irrigation is performed: not less than three buckets of water should fall under each bush. From the abundant autumnal application of fluid depends on whether the plant will bloom buds or not. It is desirable to carry out the same watering in the spring, in the beginning of April.
Soil mulching
The soil for planting rogers should be rich in nitrogen. With enough of this element, the leaves of the plant grow large, fleshy and very beautiful. For enrichment of soil mixtures with nitrogen they add humus and soil taken from under the leaf trees. In such a land is leaf humus and not rotted foliage. By mixing these components, light, loose and aerated soil is obtained. It will not stagnate excess moisture and oxygen can be supplied to the roots of the plant.
In early spring, when the roger seedlings rise above the ground by 5 - 10 cm, the soil at the foot of the bush is mulched. Mulch prevents the evaporation of moisture, weed growth and in some cases fertilizes the bush itself.
Did you know? As mulch for plants can serve: sawdust, peat powder, clay, paper, gravel, straw, pine needles or pine cones.
What to spend feeding
Rogers can grow on nitrogen-poor soils. But, if you want to see a really powerful and beautiful plant in your garden, you will have to feed. During the season, the plant is twice fed with a complex fertilizer containing in equal proportions potassium, nitrogen and phosphorus. The first such feeding is carried out before the start of flowering of Rogers, and the second immediately after the end of this period. For dressing use the most diverse organic fertilizer: mullein, bird droppings or ready-made liquid organic extracts (you can buy them in specialized stores).
Using natural organic, the gardener needs to first make fermented infusions from it and only then, spreading them with water, apply for dressings:
- Korovyak taken in the following proportions: 0.5 buckets of fresh mullein are poured to the top with water, mixed and closed. The swill is fermented for two weeks. For irrigation in a bucket of water, add 2 liters of ready slurry.
- Bird droppings are used as follows.: 1/3 part of fresh or dry litter is placed in a bucket and filled with water to the top, then stirred and tightly closed. Ferment infusion for at least 10 days. For watering take 0.5 liters of ready-to-use liquid and diluted in a bucket of water.
Important! When preparing fermented concentrated fertilizers, the dosage of the mixtures must not be disturbed. If you exceed the rate of fertilizer -You can burn the roots of the plant.
Rogers use in landscape design
Rogers in landscape design is widely used for landscaping park alleys. The plant is planted in a composition with other decorative flowers and shrubs. The large-leaved and Rogers "Heinrici" planted near the host look good. With the help of Rogers, the shady corners of gardens and parks are made by combining the bushes of a plant with a Brunner or Darmer.
Rogersia, lined with flowering geraniums or miners - will be the central, vibrant composition of your garden. In places with a slight shading from the sun's rays, Rogers Nepalese are planted, which, in combination with the lashes of a blossoming delphinium, wand, Veronica, buzulniki, daylilies and badan creates unique mixborders.
Barberry Turnberg with maroon-copper or beige leaves in combination with silver sucker effectively combined with the bright green foliage of rogers. In single plantings, this plant looks no worse than in group, mixed flowerbeds. When planning flowerbeds with rogers, you can combine its bushy bushes with thin and tall ornamental plants, for example, with astilbe of various species, ostrich birds, meadowsweet or olshanka. Also in the composition will look good one or more large smooth stones. 
Rogersiya combines the elegant green of large leaves and the modest unobtrusiveness of panicled flowers. It can be planted as a hedge, with which it is easy to draw the shores of ponds and artificial lakes. Rogersiya landed at the gazebos, benches or swings.
Resistance to pests and diseases
Rogersia practically does not get sick. Only sometimes a rust fungus can appear on its gorgeous leaves. The parts affected by the fungus must be cut out and the plant treated with any fungicide. Spraying is best done in the morning or evening, on a dry leaf and at a temperature not higher than + 25 ° C. When the Rogers' bush is planted in the marshy lowlands, the plant root rot disease can occur.
To get rid of this problem, only transplanting to a drier place or digging up a bush with a subsequent device in the drainage pit will help. To create it, you can use fragments of thick branches, expanded clay, fragments of pottery. When drainage is arranged at the bottom of the pit to drain excess moisture, you can plant a bush back. 
Slugs and snails are the main pests of Rogers. To combat them, the leaves and the soil under the plant are sprinkled with dry mustard. Mustard powder is made early in the morning, so that the substance has time to stick to the leaves, covered with morning dew.
How to protect from winter cold and spring frosts
For the winter, the green mass of Rogers is cut off near the ground. In case the winter is harsh and the snow cover is shallow, the root circle of the bush is covered with leaf litter or rotted humus. Peat is also suitable for this purpose. Winter hardiness of Rogers is very doubtful, and early varieties may suffer from the May night frosts.
Therefore, it is better to cover them with agrofiber or spunbond for the night. Late varieties of Rogers are not so susceptible to freezing, because their first shoots appear only at the end of May, when return frost is not terrible. These include Die Schone, Die Stolze, Die Anmutige, Spitzentanzerin or White Feathers. 
Such an ornamental plant can not be forgotten in the design of the landscape of gardens and parks. With its virtues and beauty, it will rightfully take a leading role in the plant supplement of park areas, and its effective appearance can only be skillfully emphasized by its proximity to other garden plants.
