Summary

Caragana arborescens, commonly known as Siberian Peashrub, is a deciduous shrub or small tree native to open woodlands and steppe regions in Central Asia and Siberia. It typically grows to a height of 2–6 m (6 ft 7 in – 19 ft 8 in) with a moderate to fast growth rate, adding one to three feet annually after trimming. The plant features alternate, compound leaves with numerous small leaflets, ranging from light to dark green. In May or June, it produces fragrant yellow flowers that are attractive to bees, followed by legumes containing seeds that twist and pop open as they dry in July.

Siberian Peashrub is valued for its nitrogen-fixing ability, making it beneficial for soil enrichment. It is often used in erosion control, as an ornamental plant, and for bonsai. Its extensive root system makes it suitable for outer rows in multi-row plantings and single-row field windbreaks where a dense, short barrier is desired. It thrives in full sun, requires medium amounts of water, and grows well in soils with medium to slow drainage. However, it can be invasive outside its native range, so it is important to check local regulations before planting.CC BY-SA 4.0
