Senna odorata, fragrant senna, spreading cassia or southern cassia, is a species of flowering plant in the legume family.

Description

S. odorata can usually reach a height of 1.5–2.4 m (4 ft 11 in – 7 ft 10 in), but this upright perennial shrub may become a tree.[2] It has paripinnate alternate leaves, with six to 12 pairs of leathery textured, slender, oval leaflets. Flowers are bright yellow and cup-shaped, arranged in small clusters. They are lightly fragrant (hence the scientific epithet odorata of the species, meaning odorous). The flowering period extends from midspring to early summer. The fruits are flat legume pods with many small seeds.[3][4][5]
