Senna odorata

Yellow flowers

S. odorata can usually reach a height of 1.5–2.4 m (4 ft 11 in – 7 ft 10 in), but this upright and sprawling perennial shrub may become a tree.[3] 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 or in panicles. They are lightly fragrant (hence the specific epithet odorata, meaning odorous). The flowering period extends from late winter to spring. The fruits are flat legume pods with many small seeds.[4][5][6]

This species is native to the forest edges of Australia (southern Queensland, south to New South Wales), usually in dry sclerophyll forest. It has been introduced in India and Mauritius.[4][7]

In its habitat, the plant can tolerate drought, light frost and high wind.[8]
