Siberian Peashrub is an upright shrub that can be trained into a small tree. It has showy yellow pea like flowers that appear in late May. Bark of the trunk and stems retain a greenish color for several years. The small leaflets of the pinnately compound leaves are medium green in color. Often used as a windbreak or tall informal hedge.

Requirements and Culture:
Needs full sun and a well drained soil for good performance. Requires little maintenance. Very tolerant of drought, cold winter temperatures, and poor soil conditions. Has good tolerance to alkaline soils and deicing salt. Not bothered by rabbits.

Limitations:
Not tolerant of poorly drained soils. Susceptible to leaf spot diseases, blister beetles and red spider mites which leads to poor foliage quality in mid to late summer. This species has limited ornamental qualities, but is valuable for planting in difficult growing conditions.

Selected Cultivars:

'Sutherland'- has a more narrow, upright form.

C. microphylla'Tidy'- is a compact variety with smaller leaves than that of C. arborescens.
