Castanospermum australe

Moreton Bay Chestnut
Fabaceae (Leguminosae)
Evergreen, Trees

Native to Australia. Beautiful in foliage; spectacular in flower. To 50–60 ft. tall, nearly as wide. Large, shiny, dark green leaves are divided into 11–15 leaflets about 1 1/2 by 5 in. Bright red-and-yellow flowers in stiff spikes about 8 in. long; they grow from twigs, branches, and main trunk in summer. Seeds look like chestnuts but are toxic raw; they may be eaten safely if roasted but don’t taste very good. Good lawn or waterside shade tree. Little pruning required.
