Rogersia (lat. Rodgersia) is a perennial flowering plant belonging to the Saxifraga family. Its homeland is Japan and China. But, despite this, the plant has taken root in Russia, and now its popularity is growing every year. This is explained by the unpretentiousness of the perennial, high decorative qualities, which is confirmed by the photo and description of Rogers, as well as the ability to fully develop in places where garden crops usually do not survive. But for this you need to plant and provide care taking into account the requirements of the culture.
What does Rogersia look like?
This culture belongs to the category of ornamental flowering. The perennial forms a spreading dense bush, 1-1.5 m high.It is based on large dissected leaves, the petioles of which grow from an underground scaly rhizome. Each of them consists of 3-9 separate segments. Their edges are double serrated and their tips are pointed.
The veins on the Rogersia plates are strongly pronounced. Leaf shades range from dark green to bronze, metallic and even brown, depending on the species. Active vegetation of the perennial occurs after the end of the flowering period.
The root system is taproot type. In young plants it is highly developed. But as the bush matures, it changes into a stem and becomes overgrown with adventitious shoots. Over time, thick rhizomes grow directly on the surface of the soil and are able to cover fairly large areas.
Rogersia flowers are small and in most cases have no petals. The buds are collected in paniculate inflorescences that confidently rise above the foliage. Their shade varies from white, yellow to pink, red. Flowers emit a pleasant aroma that attracts the attention of pollinating insects. The fruits are presented in the form of two-nest boxes.
When does Rogersia bloom?
The flowering period of this perennial begins in mid-July and lasts for 4-6 weeks. Its timing may shift by 7-10 days, depending on the growing region.
Types and varieties of Rogers with photos and descriptions
In nature, there are about five species of perennials that are widely used in gardening. Rogersias differ in the color of the flowers, as can be seen in the photo, the shade of the leaves and the structure of the plates. To be able to identify each species, you need to study its characteristic features.
horse chestnut leaf
This type of culture is characterized by the largest leaves and strong petioles.The plant fully lives up to its name, since the shape of its plates is similar to horse chestnut. The bushes are round, compact. Horse chestnut-leaved Rogersia (Rodgersia aesculofolia) forms flower stalks in early July, the height of which reaches 120-150 cm. The flowers of the perennial are pink-white or cream, exuding a pleasant, sophisticated aroma. The flowering period of this species lasts for a month. The rest of the time, the plant pleases with the beauty of its textured leaves, which, when blooming, are bronze and then turn green.
Centopolist
This Rogersia is found in China, Korea and Japan. Its leaves consist of 5-7 segments with serrated tips. When blooming in the spring, Rogers leaves are reddish-brown in color and later turn bronze. By autumn, their shade changes to the original one. The height of Rogersia podophylla reaches 1.6 m. The species blooms in the second half of June and continues for five weeks. The branched inflorescences are creamy white.
Cirrus
A characteristic difference of the species is that its plates can have different shapes. On the leaves of pinnate Rogersia (Rodgersia pinnata), as can be seen in the photo, the veins are clearly visible. The petioles are short, which makes the perennial similar to a palm tree. Closer to autumn, the color of the leaves changes to bronze-reddish. The height of the plant barely reaches 70 cm.
The flowering period of the feathery species begins in July. At this time, pinkish-white peduncles rise above the leaves.
Elderflower
The Chinese provinces of Sichuan and Yunnan are considered the homeland of this variety of perennial. It is most common in gardening and is characterized by unpretentiousness. The height of an adult plant barely reaches 60 cm. The bushes are round and compact. Large blades of elderberry (Rodgersia sambucifolia) have a green tint with a bronze tint. The number of leaves depends on the age of the bush and its growing conditions.
The flowering period for elderberry Rogers begins in July. The hue of large branched inflorescences is initially white, and later becomes brown.
Nepalese
This species differs from others in the structure of its leaves. They consist of segments that are located at a certain distance from each other and have a light yellow or blue-green color. The inflorescences of Nepalese Rogersia (Rodgersia nepalensis) are dense and pyramidal. They are colored lemon or light greenish. In nature, this species is rare, although it is considered the most spectacular.
When to plant Rogers
Rogers can be planted in autumn and spring. In the first case, the procedure is recommended to be done in the first ten days of September. This will allow the plant to fully take root before the onset of frost. For spring planting, the optimal period is the second half of May. By this time, the soil has time to warm up and the threat of return frosts has passed.
How to plant Rogers
In order for the plant to quickly adapt to open ground, fully develop and bloom profusely every year, it is necessary to plant Rogers correctly. Therefore, you need to study the features of the procedure in advance in order to avoid mistakes later.
Rogers planting site
For the culture, it is recommended to choose a shaded place, protected from cold gusts of wind. The best option is to place it under the canopy of trees or near buildings that will protect the leaves of the plant from direct sunlight.
When choosing a place in the garden, you also need to take into account that Rogers belongs to the category of moisture-loving crops. Therefore, it should be placed in an area where the soil rarely dries out.
The perennial prefers loose, nutritious soil rich in organic matter. Therefore, the best option for the plant is loam and black soil. It is important that the soil has good moisture and air permeability, and that the groundwater level in the area is at least 1.5 m.
Site preparation
Before planting Rogers in a permanent location, it is recommended to prepare the site at least two weeks in advance. To do this, you need to dig it up to the depth of a shovel to enrich the soil with oxygen and carefully remove the roots of perennial weeds.
Also, at the site preparation stage, you need to add humus and peat to the soil, 5 kg per square meter. m. Additionally, superphosphate 40 g and potassium sulfide 25 g must be added to the soil. After this, the area must be carefully leveled.
Landing rules
To plant a perennial, you need to prepare a hole measuring 20 by 20 cm. Place a 10 cm thick layer of drainage at the bottom, and then sprinkle the top with soil. You need to place the seedling in the center and carefully straighten its roots. Sprinkle them with soil, fill all the voids, and compact the soil at the base of the perennial. The roots of the plant should be located at a depth of no more than 5 cm.
After planting, water the plant generously. And the next day you need to mulch the root circle with a layer of humus or peat, which will eliminate the possibility of the underground part of the plant drying out.
It is necessary to plant seedlings at a distance of 1.2-1.5 m to tall crops, and when planting several plants in a row, maintain a distance of 50-70 cm, depending on the species.
Rogers care
This plant does not require complex care, so any novice gardener can cope with its cultivation. In order for it to show maximum decorativeness and maintain it for many years, it is necessary to adhere to certain rules of agricultural technology.
Fertilizer
The accelerated rate of crop growth and abundant flowering require a sufficient amount of nutritional components in the soil. Therefore, the plant needs to be fertilized twice per season, starting from the second year after planting. Since until this time it will use the components added to the soil at the site preparation stage.
In the spring, at the beginning of the growing season, it is recommended to fertilize the plant with organic matter, namely mullein 1:10 or chicken manure 1:15.Fertilizers should be applied a second time after Rogers blooms, which will increase its winter hardiness. At this time, complex mineral mixtures should be used, containing, in addition to potassium and phosphorus, components such as sulfur, copper, zinc, iron, magnesium.
Watering
For active growth of green mass and abundant flowering of Rogers, it is necessary that the soil is always moist. Therefore, perennials need to be watered regularly in the absence of seasonal rains. To do this, it is necessary to use settled water at a temperature of +18-20 °C.
Moisturize in the evening 1-2 times a week. And in especially hot periods, a layer of mulch should be laid at the base of the Rogers. This will prevent excessive evaporation of moisture from the soil.
After each watering, it is necessary to loosen the soil at the base of the perennial. This procedure will prevent the formation of a crust on the surface of the soil and will maintain air access to the roots of the plant.
Transfer
As perennial bushes grow, they gradually lose their decorative properties. This sign indicates that the Rogersia needs to be transplanted to a new location. Experienced gardeners recommend carrying out the procedure every eight years in the fall, as soon as the weather is favorable.
Does Rogersia require pruning for the winter?
It is recommended to prune Rogersia for the winter. The procedure should be carried out in late autumn after leaf fall. Rogers shoots must be shortened to a height of 30 cm.
Preparing Rogers for winter
As the perennial grows, its root system ends up on the surface, so it needs to be covered for the winter.To do this, it is necessary in late autumn, before the onset of frost, to lay a 10 cm layer of mulch in the root circle of the plant. And during the winter, throw a layer of snow over the perennial. This will allow Rogers to survive the cold season without any problems.
Rogersia propagation
To propagate Rogers, you can use seeds, cuttings, and also divide the bush. Each of these reproduction methods has certain characteristics that need to be taken into account.
Growing Rogers from seeds is a labor-intensive process, but this method makes it possible to obtain many new seedlings at the same time. Before planting, it is necessary to soak the planting material in a solution of potassium permanganate for five minutes, then rinse with clean water and dry slightly until characteristic flowability appears.
It is recommended to sow in wide containers filled with a soil mixture of turf, sand and peat, taken in equal quantities. The seeds need to be spread on the surface of the substrate, sprinkled with a 0.3 cm layer of soil and moistened with a spray bottle. After this, the container must be covered with film and placed in a bright place with a temperature of +20-24 °C. At the stage of two true leaves, Rogers seedlings must be planted in separate cups. You can plant plants in open ground when they are strong enough.
To propagate a perennial by cuttings, you need to cut the leaves with a “heel” at the beginning of summer. After this, you need to powder the lower cut with a root former, and then plant it in a mixture of peat and sand in equal quantities. It is recommended to keep cuttings at a temperature of + 20-22 ° C. The soil should be moistened regularly as necessary.
Dividing the bush is the easiest way to propagate Rogersia. The optimal period for this is early spring before the start of the growing season. To propagate, you need to carefully dig up the bush, divide it into parts with pruners and immediately plant them in a permanent place. After this, provide the seedlings with standard care.
Diseases and pests of Rogers
This culture has high natural immunity. However, inadequacy of growing conditions leads to its weakening. And then the plant may suffer from rust fungus. In this case, it is necessary to remove the affected leaves and spray the Rogersia with Bordeaux mixture. It is important to do this procedure in the morning so that the plant is completely dry by evening.
Perennials can also suffer from root rot caused by prolonged stagnation of moisture in the soil. The plant can be saved only at the initial stage of damage. To do this, you need to dig it up, transplant it to a new place and water it with Previkur Energy.
Of the pests, Rogers can be damaged by slugs that feed on its leaves. In this case, it is necessary to sprinkle thickly with wood ash or tobacco dust at the base of the plant. And in case of mass reproduction of pests, it is recommended to use special chemical protection products based on metaldehyde.
Why does Rogersia dry out?
Rogersia does not tolerate any, even slight, drying out of the root system. Therefore, most often, insufficient watering during hot periods is the cause of drying out the tips of the leaves. Dry air can also cause a problem. Therefore, it is recommended to periodically wash the leaves using the sprinkling method.
The reason that Rogersia dries out may also be a lack of potassium in the soil.In this case, a dark border appears along the edge of the plates. To correct the situation, you need to fertilize with a higher content of the required component.
