Cultivation Details

HabitDeciduous Tree
Growth—

A plant of low to moderate elevations in the drier tropics, where it can be found from sea level to over 2,000 metres. It is found mainly in areas where the mean annual temperature is from 25 - 30°c, and the mean annual rainfall is within the range 500 - 1,000mm[2, 3]. A fast-growing plant[2]. The plant responds well to coppicing[2, 3]. The plant is fairly susceptible to fire, though its thick bark does give it some protection[2]. Although many species within the family Fabaceae have a symbiotic relationship with soil bacteria, this species is said to be devoid of such a relationship and therefore does not fix atmospheric nitrogen[4].

Propagation

Seed - pre-soak in warm water for 12 hours prior to sowing. The seed usually sprouts within 9 days of sowing, with around 78% germinating[2]. Cite as: Tropical Plants Database, Ken Fern. tropical.theferns.info. 2026-02-20. <tropical.theferns.info/viewtropical.php?id=Senna+singueana>
