Description

Butea monosperma is a small-sized dry-season deciduous tree, growing to 15 m (49 ft) tall. It is slow-growing: young trees have a growth rate of a few feet per year. The leaves are pinnate, with an 8–16 cm (3.1–6.3 in) petiole and three leaflets. Each leaflet is 10–20 cm (3.9–7.9 in) long. The flowers are 2.5 cm (0.98 in) long, bright orange-red, and produced in racemes up to 15 cm (5.9 in) long. The fruit is a pod 15–20 cm (5.9–7.9 in) long and 4–5 cm (1.6–2.0 in) broad.

The flowers frequently have a spectacular bloom sometime from February to April, although the trees do not flower every year. Each flower features five petals, two wings, and a keel that resembles the curled beak of a parrot. If the winter season is too cold, too dry, or too rainy, trees may not blossom.
