The Sorbaria is a member of the pink family. In nature, such plants are found in Asia. This genus has only 10 species. The name of this plant comes from the Latin word "Sorbus", which translates as "rowan". The fact is that the leaf plates of representatives of this genus are very similar to the leaves of the common mountain ash.
As an ornamental plant, the mountain ash has been cultivated since the middle of the 18th century.
Peculiarities of the mountain ash
The mountain ash is a deciduous shrub that can reach about 3 meters in height. It can form very beautiful dense thickets because it grows many root shoots. The elbow-shaped, twisted stems are colored gray-yellow. The unpaired, compound leaf laminae include 9 to 13 pairs of twice serrated or serrated leaves.
Pyramidal, panicle-shaped inflorescences consist of many small cream or white flowers. The fruit is a leaflet.
This type of shrub is used in landscape design for making group and solitary plantings and also for hedges, for decorating ponds as well as for fixing slopes.

When to plant
Put outdoors in early spring before the sap starts or after the fall leaves have ended.
This plant is relatively shade-loving so it can be planted under tall trees. It thrives equally well in very moist soil and in clayey, heavy soil.
How to plant
The size of the planting hole should be approximately 0.7 x 0.7m and not more than 0.
5m deep. If you create a group planting, the distance between the specimens should be not less than 100 centimeters. The rowanberry is similar to thorns in that it can quickly grow, capturing more and more territory, so the sides of the planting hole are recommended to cover with slate or metal sheets. At the bottom of the hole it is necessary to make a good drainage layer. It should be covered with a layer of earth mixture consisting of soil combined with humus or compost.
Then the root system of the seedling should be placed in the hole, and it should be covered with soil combined with organics. During planting make sure that the root neck of the plant is 20-30 mm above the surface of the plot. The planted shrub should be watered, with 20 liters of water poured under it. When the liquid has been completely absorbed into the ground, cover the surface of the planting area with mulch.
Powering the Mountain Ash
Garden care of Mountain Ash
The care of Mountain Ash is very easy and even a beginner can handle it.
Remember that the soil near the shrub should always be slightly damp and loose. Provide it with timely removal of root growth and weeds, and regularly feed (when growing in poor soil). Trim finely only if necessary.
Pour liberally, especially if you are experiencing a long dry spell. Fertilize in small portions at least twice a season, either by embedding the nutrient mixtures lightly or superficially.
Fertilizing should be done with compost, peat or humus; in some cases even with complex mineral fertilizers.
To ensure the plant appearance always remains as impressive as possible, the withered inflorescences should be cut off in time. At the very beginning of the spring period sanitary pruning should be done by cutting out all traumatized, pest or disease damaged, dried out branches and those that overgrow the bush. If you do not thin the bush, the stems will become thinner, weaker, and they will age very quickly. Pruning the rowanberry tolerates well, even rejuvenating.
Remember to cut out the root shoots systematically.
The shrub tolerates transplanting very well. This procedure is very often done together with the division of the shrub. A new planting hole should be prepared in the autumn or spring. At its bottom it is necessary to place a drainage layer, and also it is necessary to prepare a soil mixture consisting of the soil taken out of the hole, and also of compost or humus.
Remove the bush from the ground, and if necessary, cut it into several parts, taking into account that each partition should have strong shoots and well-developed roots. The places of the cuts should be sprinkled with crushed charcoal, then the dividers are planted in new places. If you do not make the division of the bush, then the dug plant will need to be placed in a planting hole, which is filled with prepared soil mixture. The soil around the shrub is tamped down and then abundant watering is done.
Replication of rowanberry
This plant can be multiplied by bush division, this procedure is described in great detail above.
Theoretically, the rowanberry can be propagated by seeds, but in practice seedlings appear very rarely. More often gardeners propagate this shrub by single-tree cuttings and grafts.
To propagate rowanberry by grafts is very simple and easy. In spring you should choose a sturdy, healthy and long stem and bend it towards the ground so that a few buds are in contact with it. Then the stem is fixed in this position and covered with soil, leaving its top free.
Don't forget to water the branched off stem in good time during the summer. After a few weeks the propagules will have rooted out and in late summer or early autumn they can be cut off from the parent plant and planted in a new location. For rooting, they are planted in a box filled with earth mixture. Make sure that the soil is slightly moist all the time. If the cuttings root successfully, their tops should start to grow.

Diseases and pests
This shrub has high phytoncidal properties, which explains its resistance to diseases and pests. Very rarely green aphids or spider mites may settle on it. Such sucking insects suck plant sap from the bush, resulting in its sluggishness, as well as deformation of the stems and yellowing of the leaves.
In addition, there is a high probability that such pests infect rowanberry with viral mosaic. Such a disease is not curable, and therefore you will only have to dig up and destroy the plant. Treat the infested specimen with Fytoverm or Mitaka solution to get rid of such insects.
When flowering ends, you should cut off all fading inflorescences. Once the foliage is over, the dried leaves should be collected and destroyed.
Mountain ash is extremely frost hardy, even suffering severe frosts.
Rhoeberry species and cultivars with pictures and names
Cultivated only 4 species:
Whoeberry (Sorbaria tomentosa)
This species is native to Eastern Asia. This plant can reach a height of up to 6 meters. In nature, the shrub prefers to grow on mountain slopes. It does not flower.
Its cold tolerance is low.
Wood elm (Sorbaria arborea)
In nature, it occurs in East Asia. The height of such a shrub does not exceed 6 meters. This slow-growing plant is highly frost-resistant. Flowering occurs in July-August.
Pallas's-marrow (Sorbaria pallasii)
This plant can be found in nature on rocky slopes in Transbaikalia and the Far East. The height of this showy mountain ash does not exceed 1.2 m. Young stems are brown in color and naked or finely pubescent with branched light yellow hairs. Older stems are covered with peeling bark.
The nonparietal linear-lanceolate leaf blades are up to 15 centimeters long and usually covered with reddish hairs. The not-so-large apical panicle-like inflorescences consist of white or cream-colored flowers, which are 1.5 cm in diameter. The fruit is a pubescent leaflet. This shrub is winter-hardy.
Corbifolia (Sorbaria sorbifolia)
This species is most popular with gardeners. In the wild it forms thickets on riverbanks and forest edges in the Far East, Korea, Siberia, China and Japan. The height of the shrub does not exceed 200 centimeters. The color of the straight stems is brownish-gray. The pointed, unpaired pinnatipartite leaf leaves are about 0.
2 m long and have a pointed apex. The leaves are orange-pink when they first open, pale green in summer, changing to crimson-red or yellow in autumn. Pyramidal panicles are no more than 0.3 m long and have fragrant, cream-colored flowers. They have very long stamens, which makes the inflorescences look fluffy.
The fruit is a fused, jug-shaped leaflet.
