Siberian Pea Tree

• If the Siberian pea tree (Caragana arborescens) handles a Siberian winter, it will grow in North America's cool U.S. Department of Agriculture plant hardiness zones. This deciduous shrub grows to 20 feet, featuring compound leaves, yellow flowers and hanging seedpods. Able to grow into USDA zone 2, where winters are traditionally fierce, Siberian pea tree is an option for cool-weather sites as a windbreak, privacy screen or hedge.
