Caragana arborescens (Siberian Pea Tree)

Caragana arborescens (Siberian Pea Tree) is a deciduous shrub or small tree that is native to Siberia and parts of Asia. It is widely cultivated in gardens and as a hedge plant in many parts of the world due to its attractive yellow flowers, hardiness, and ability to tolerate a wide range of growing conditions. 

The plant typically grows to a height of 3-6 meters, with a spread of 3-4 meters. It has a rounded, bushy form and a dense crown of small, bright green leaves that turn yellow in the fall. The bark is grayish-brown and develops deep fissures as the tree ages. 

In late spring to early summer, the Siberian Pea Tree produces clusters of bright yellow pea-like flowers that are highly fragrant and attractive to pollinators. The flowers give way to long, narrow seed pods that contain several small, hard seeds. 

The Siberian Pea Tree is a tough, hardy plant that is tolerant of drought, poor soil, and cold temperatures. It is commonly used as a windbreak or as a hedge plant, and is also planted in urban areas as a street tree.
