Sesbania grandiflora

Sesbania grandiflora is a fast-growing tree. The leaves are regular and rounded and the flowers white, red or pink. The fruits look like flat, long, thin green beans. The tree thrives under full exposure to sunshine and is extremely frost sensitive.

It is a small soft wooded tree up to 4–16 m (13–52 ft) tall. Leaves are 15–30 cm (6–12 in) long, with leaflets in 10–20 pairs or more and an odd one. Flowers are oblong, 1.5–10 cm (1–4 in) long in lax, with two to four flower racemes. The calyx is campanulate and shallowly two-lipped. Pods are slender, falcate or straight, and 30–45 cm (12–18 in) long, with a thick suture and approximately 30 seeds 8 mm (0.3 in) in size.

It is native to Maritime Southeast Asia (Malaysia, Indonesia, Philippines, Brunei) to Northern Australia, and is cultivated in many parts of South India and Sri Lanka. It has many traditional uses.[5] It grows where there is good soil and a hot, humid climate.

It is used to make highly nutritional fodder for ruminants like cattle, though it can be deadly to chickens.[6]
