What is Caragana?
Cararagana , most often known as the Siberian pea shrub, is a genus of shrubs or small trees that come from cold, semi -dry areas of Siberia in Russia and Manchuria region in northeastern China. They were also imported and extensively set in Canada and the northern part of the United States such as windbreakers and screenings. The pea shrub is also resistant in poor soils, fast growing and tolerant to extreme cold and drought; He is able to prosper in a harsh landscape where many other trees and shrubs cannot. In addition to helping to prevent wind erosion, caragana also provides wildlife stands for livestock, especially sheep and camels.
This genus includes more than 100 species of shrubs and small trees, of which the Caragana Arborescens is a commonly known Siberian pea shrub or pea tree. 'Walkeri' is one variety of peas shrub, which has a crying form, which makes it more popular for ornamental and landscape use. "Lorbergii," "Nana" and "Pendula" are some otherVarieties that are grown as ornamental shrubs. When used as an ornamental bush form, it can be changed by selective pruning as it grows.
Generally, the caragana grows to a height of 10 to 15 feet (3.1 to 4.6 meters) with a somewhat narrower span. It has an upright form with branches with multiple traces and small leaves in the shape of an oval. Deciduous leaves are bright green over spring and summer and gold in autumn. In May there are small yellow flowers, which are replaced during the summer with elongated seed pods. According to tan or brown, when they ripen, and make the sound of cracking when they tear at the end and autumn.
6 also has a large root branching system; Both these features make caragana an excellent choice for land holding and reducing wind erosion from fields. caragana can live up to 50 years but must be cut back every three or four years to keep their strong leaves and SCREening properties.in China, Cararagana was widely used in land reclamation projects. Extensive roots protect from sand erosion, but also help prevent water erosion on slopes when planted by a terrace pattern. caragana also has the properties of nitrogen fixation and adds an organic mass to the soil in the form of a leaf and a litter of litter. Previously poor lands were improved by planting and maintaining large groves of peas.
Caragana is also an important source of nutrition for wild animals as well as grazing domesticated herds of sheep, goats, camels and reindeer. In a cold climate, the pea shrub provides a leaf and a bark through the winter, when the grass is covered with prairia wsni. Seeds can also be harvested in autumn and fed into animals in the winter months. The plant itself benefits from periodic "pruning" provided by animal pastures. Pruning promotes stronger growth of the following spring.
