Rogersia: photos in landscape design, varieties and species with a name, cultivation

Rogersia (lat. Rodgersia) is a perennial flowering plant belonging to the Saxifrage family. It is native to Japan and China. But, despite this, the plant has taken root in Our Country, and now its popularity is growing every year. This is due to the unpretentiousness of the perennial, high decorative qualities, which is confirmed by the photo and description of Rogersia, as well as the ability to fully develop in places where horticultural crops usually do not survive. But for this you need to land 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 sprawling 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 twice serrated, and the tops are pointed.

Veins are strongly pronounced on the plates of Rogersia. The shade of the leaves varies from dark green to bronze, metallic and even brown, depending on the species. Active perennial vegetation occurs after the end of the flowering period.

Root system of rod type. In young plants, it is highly developed. But as the bush grows older, it changes into a stem and becomes overgrown with adnexal processes. Over time, thick rhizomes grow directly on the surface of the soil and are able to cover fairly large areas.

Rogersia flowers are small, in most cases they do not have petals. The buds are collected in paniculate inflorescences, which confidently rise above the foliage. Their shade varies from white, yellow to pink, red. Flowers exude a pleasant aroma that attracts the attention of pollinating insects. The fruits are presented in the form of two-nested boxes.

When Rogersia Blooms

The flowering period of this perennial begins in mid-July and lasts for 4-6 weeks. Its terms can be shifted by 7-10 days, depending on the region of cultivation.

Types and varieties of Rogersia with photos and descriptions

In nature, there are about five types of perennials that are widely used in horticulture. Rogers are distinguished by 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 justifies its name, since the shape of its plates is similar to horse chestnut. Bushes rounded, 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, exude a pleasant, refined aroma. The flowering period of this species lasts for a month. And the rest of the time, the plant pleases with the beauty of its textured leaves, which, when blooming, are bronze, and then turn green.

In the horse-chestnut-leaved variety, the stem and sepals are covered with black hairs.

stopopolistnaya

This Rogersia is found in China, Korea and Japan. Its leaves consist of 5-7 segments with notches at the tips. When blooming in spring, Rogersia plates have a reddish-brown color, and subsequently become bronze. By autumn, their shade changes to the original. The height of Rogersia stopifolia (Rodgersia podophylla) reaches 1,6 m. The species blooms in the second half of June and continues for five weeks. Branched inflorescences are creamy white.

Stopoli Rogersia is also called podophyllous.

Cirrus

A characteristic difference of the species is that its plates can have a different shape. On the leaves of the feathery Rogersia (Rodgersia pinnata), as can be seen in the photo, veins are clearly distinguished. The petioles are short, which makes the perennial similar to a palm tree. Closer to autumn, the color of the leaves changes to a bronze-reddish. Plant height barely reaches 70 cm.

The flowering period of the pinnate species begins in July. At this time, pinkish-white peduncles rise above the leaves.

Rogersia pinnate is considered the most drought-resistant

Elderberry

The homeland of this variety of perennial are the provinces of China Sichuan and Yunnan. 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, compact. Large plates of Elderberry Rogers (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 of elderberry Rogersia begins in July. Hue of large branched inflorescences is initially white, and later becomes brown.

In elderberry Rogersia, the color of the leaves does not change throughout the season.

Nepalese

This species differs from others in the structure of the 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 the Nepalese Rogersia (Rodgersia nepalensis) are dense, pyramidal. They are painted in a lemon or light greenish hue. In nature, this species is rare, although it is considered the most spectacular.

When to plant Rogersia

Rogersia can be planted in autumn and spring. In the first case, the procedure is recommended to be done in the first decade of September. This will allow the plant to fully take root before the onset of frost. For spring planting, the second half of May is the optimal period. By this time, the soil has time to warm up and the threat of return frosts has passed.

How to plant Rogersia

In order for the plant to quickly adapt in the open field, fully develop and bloom profusely every year, it is necessary to properly plant Rogersia. Therefore, it is necessary to study the features of the procedure in advance in order to avoid mistakes later.

Rogersia landing site

For culture, it is recommended to choose a shady place, protected from cold gusts of wind. The best option is to place 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 consider that Rogersia belongs to the category of moisture-loving crops. Therefore, you need to place it in an area where the soil rarely dries out.

Perennial prefers loose nutrient soil rich in organic matter. Therefore, the best option for the plant are loams and black soil. At the same time, it is important that the soil passes moisture and air well, and the groundwater level in the area is at least 1,5 m.

Herbaceous shrub prefers a slightly acidic or neutral substrate

Site Preparation

Before planting Rogersia in a permanent place, it is recommended to prepare the site at least two weeks in advance. To do this, you need to dig it to the depth of a shovel to enrich the soil with oxygen and carefully remove the roots of perennial weeds.

Also, at the stage of site preparation, it is necessary 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 that, the site must be carefully leveled.

Rules of landing

To plant a perennial, it is necessary to prepare a hole measuring 20 by 20 cm. Put a layer of drainage 10 cm thick on the bottom of it, and then sprinkle it with earth on top. In the center you need to place a seedling, gently straighten its roots. Sprinkle them with earth, fill in all the voids, 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.

Water the plant thoroughly after planting. And the next day, you need to mulch the root circle with a layer of humus or peat, which will eliminate the possibility of drying out the underground part of the plant.

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, keep a distance of 50-70 cm, depending on the species.

As it grows, Rogersia is able to suppress the development of neighboring crops.

Rogersia Care

This plant does not require complex care, so any novice gardener can handle its cultivation. In order for it to show maximum decorativeness and retain it for many years, it is necessary to adhere to some rules of agricultural technology.

Fertilizer

The accelerated rate of crop vegetation and abundant flowering requires a sufficient amount of nutrients in the soil. Therefore, you need to fertilize the plant twice per season, starting from the second year after planting. Since until that 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. The second time you need to apply fertilizer after the flowering of Rogersia, which will increase its winter hardiness. At this time, complex mineral mixtures containing, in addition to potassium and phosphorus, components such as sulfur, copper, zinc, iron, and magnesium should be used.

Watering

For active growth of green mass and abundant flowering of Rogersia, it is necessary that the soil is always wet. Therefore, perennials should be watered regularly in the absence of seasonal rains. For this, it is necessary to use settled water with 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 Rogersia. 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. Such a procedure will prevent the formation of a crust on the surface of the soil and maintain air access to the roots of the plant.

Transfer

As the perennial bushes grow, they gradually lose their decorative effect. This sign indicates that Rogersia needs to be transplanted to a new place. Experienced gardeners recommend carrying out the procedure every eight years in the fall, as soon as favorable weather sets in.

Does Rogers require pruning for the winter

It is recommended to cut Rogersia for the winter. The procedure should be carried out in late autumn after leaf fall. It is necessary to shorten the shoots of Rogersia to a height of 30 cm.

Preparing Rogers for Winter

As the perennial grows, its root system is on the surface, so it needs to be covered for the winter. To do this, in late autumn, before the onset of frost, lay mulch with a layer of 10 cm 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.

Reproduction of Rogersia

To propagate Rogersia, you can use seeds, cuttings, and also divide the bush. Each of these breeding methods has certain features that need to be considered.

Growing Rogersia from seeds is a laborious process, but this method makes it possible to get 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, and then rinse with clean water and dry slightly until characteristic flowability appears.

Sowing is recommended to be carried out in wide containers filled with a mixture of turf, sand and peat, taken in equal quantities. Seeds need to be spread on the surface of the substrate, sprinkled with a layer of earth 0,3 cm and moistened with a spray bottle. After that, the container must be covered with a film and placed in a bright place with a temperature of +20-24 °C. At the stage of two true leaves, Rogersia seedlings must be dived into separate cups. You can plant plants in open ground when they are strong enough.

Under all conditions, Rogersia seeds germinate in 14 days

To propagate a perennial by cuttings, it is necessary to cut the leaves with a “heel” in early summer. After that, you need to powder the lower cut with a root former, and then plant it in a mixture of peat and sand in the same amount. It is recommended to keep the cuttings at a temperature of + 20-22 ° C. As necessary, the soil should be regularly moistened.

Dividing a bush is the easiest way to propagate Rogersia. The optimal period for this is early spring before the start of the growing season. For reproduction, it is necessary to carefully dig a bush, divide it into parts with a pruner and immediately plant them in a permanent place. After that, provide seedlings with standard care.

Diseases and pests of Rogersia

This culture has a high natural immunity. However, the inconsistency of growing conditions leads to its weakening. And then the plant can suffer from a rust fungus. In this case, it is necessary to remove the affected leaves and spray Rogers with a Bordeaux mixture. It is important to do the procedure in the morning so that the plant is completely dry by the evening.

Also, the perennial may suffer from root rot caused by prolonged stagnation of moisture in the soil. You can save the plant only at the initial stage of the lesion. To do this, you need to dig it out, transplant it to a new place and water it with Previkur Energy.

Of the pests, slugs that feed on its leaves can cause damage to Rogersia. In this case, it is necessary to sprinkle thickly with wood ash or tobacco dust at the base of the plant. And in the case of mass reproduction of pests, it is recommended to use special chemical means of protection based on metaldehyde.

Why Rogersia dries

Rogersia does not tolerate any, even a slight drying of the root system. Therefore, most often insufficient watering during hot periods is the cause of drying of the tips of the leaves. Dry air can also cause a problem. Therefore, it is recommended to periodically wash the leaves by sprinkling.

The reason that Rogersia dries may 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, it is necessary to carry out top dressing with a high content of the necessary component.
