Buddha's hand citron tree

The tree is small and shrubby with an open habit. It is very frost-sensitive. Citron leaves are distinctive in form, being oblong and somewhat rumpled, with serrate margins. The flowers and new leaves are heavily tinged with purple. The very small immature fruits may also be flushed with purple, so that they appear almost brown. The 6- to 12-inch fruits split longitudinally at the end opposite the stem, as the carpels separate into segments that look somewhat like human fingers.
