(Caragana arborescens)
A multi-stemmed upright growing shrub covered with delicate yellow flowers in spring, followed by small edible seedpods which can be eaten as a vegetable. By late summer the dried seedpods snap open, dropping the seeds which are 36% protein and make good chicken feed. So it is sometimes planted in poultry yards. However, the main benefits this super tough and cold hardy plant provides are:
1. As a nitrogen fixer, adding nitrogen to the soil wherever its roots
grow and its leaves decay, which can benefit neighboring plants.

2. As a windbreak or an impenetrable hedge (it is quite thorny). It is maintenance free and will tolerate poor soils, drought and salt as long as the site is reasonably well drained.

Mature size is approximately 4-6 meters (14-20') high and is almost as wide.
