“Underwhelming” is probably the best adjective to describe this extremely hardy plant. Neither the small yellow-pea like flowers nor the pods or leaves will probably excite you, but if you need a tough plant tolerant of salt, wind, poor, dry soil, or extreme cold, you might want to consider this small tree or shrub. And not only does it tolerate poor soil, it actually improves it by fixing nitrogen, as other members of the pea family do. Its upright, multi-stemmed, columnar habit and bright green leaves make it a good choice for a screen, informal hedge, or windbreaker as well as for borders and containers. Several cultivars with attractive characteristics have been developed. The genus name, Caragana, is the Latinized version of the Mongolian name for the genus. The specific epithet, arborescens, is the the Latin word meaning woody.
