Flowers usually rosy purple, large and showy, the flower buds 5-angled, appearing when the tree is in leaf.

Petals 1½ - 2 in. long. Stamens 3 or occasionally 4 fully developed. Pod 6 to 10 in. long ¾ inch wide, bursting suddenly when dry, the valves spirally twisting owing to the unequal tension within which occurs during drying and ultimately causes the pod to burst and throws the seeds away from the tree.
