An extremely rare Chinese cousin to North America's Kentucky Coffee Tree. Almost extinct in China and nearly unheard of in cultivation whether in public, private gardens and arboretums. Form is very much like its North American cousin in size and form, except for its remarkable foliage that starts life a royal purple then becoming blue green but retains its purple tint on the reverse. Leaflets are more perfectly oval than lanceolate like is North American kin. Totally unique. Hardiness testing proves this species can survive in pots without protection to -12C without any damage.
