Colutea

Colutea L.

Colutea is an Old World genus of 28 species, mainly distributed in Eurasia and northeastern Africa. Some species are rather frequently planted as ornamentals in Europe (Cullen 1995, Roloff & Bärtels 2006) but only the two taxa treated in this account seem to be widespread in cultivation.

  • Corolla yellow (often with reddish veins). Keel 16-20 mm long, not beaked === 1. C. arborescens
