[edit] Description

Flowers sprouting from old growth.

This species forms a small tree up to 12 metres in height and 10 metres in width. The deep pink flowers are produced on year-old or older growth, including the trunk in late spring. The leaves appear shortly after the first flowers emerge. These are heart-shaped with a blunt apex, which occasionally has a shallow notch at the tip. The tree produces long flat pods that hang vertically.

[edit] History

There is a longstanding myth that Judas Iscariot hanged himself from a tree of this species. This belief is related to the common name "Judas Tree" which is possibly a corrupted derivation from the French common name, Arbre de Judée meaning tree of Judea, referring to a region where the tree occurs.
