The Common pea shrub ( Caragana arborescens ), and pea shrub or Common pea shrub called, is a kind of family of legumes (Fabaceae), subfamily Pea (Faboideae). It is one of the larger representatives of the genus of the pea bushes .
Appearance
The pea bush is a deciduous , heavily branched and upright shrub. It can reach a height of four to six meters. Young shoots of the shrub are initially hairy and later glabrous. The bark is olive green to brownish gray in color.
The pair of pinnate leaves are alternate . The individual leaflets are 1 to 2.5 centimeters long and yellow-green in color. The pale yellow flowers appear from May to July and are up to 2.5 inches long. From them develop up to 5 centimeters long, narrow pods of reddish color.
Chromosome number
The number of chromosomes is 2n = 16.
Distribution area
The common pea bush is native to northeast Asia from Manchuria to Siberia . It copes well with cold winters and hot, dry summers. It was introduced as an ornamental plant in Europe and North America , where it is a neophyte. In Eastern Europe it occurs in societies of the Prunion fruticosae association.
use
With suitable soil and climatic conditions, the pea bush can be used as a load-bearing component in windbreak strips. In the case of pea bushes, which are offered in the garden trade as a high trunk, it is usually a refinement of the common pea bush with the dwarf pea bush .
Toxicity
The seeds were used as poultry feed in the past and as human food in times of need. Due to gastrointestinal complaints of some children, which were probably caused by the consumption of raw semen, the BfR considers this to be wrong and sees a need for further research due to a lack of reliable knowledge.
