Notably resistant to honey fungus.

From Seed, best sown as soon as ripe. Flowers are hermaphrodite and are pollinated by Bees.

Also by half-ripe cutting or layering.

More ornamental than Caragana arborescens and other species and probably a better garden plant.
Can be trained as hedging.
Used in China to stabilise sandy areas.

Native to Siberia, Mongolia and Northern China.
Like other plants of this family, it has the ability to fix nitrogen in the soil by a symbiotic relationship with certain soil bacteria.
