Cultivation:

A plant of the tropics and subtropics, where it is found at elevations up to 2,000metres. It grows best in areas where annual daytime temperatures are within the range 25 - 35°c, but can tolerate 15 - 40°c. It can be killed by temperatures of -1°c or lower

. It prefers a mean annual rainfall in the range 500 - 1,500mm, but tolerates 300 - 4,100mm
Succeeds in full sun and in light shade. Plants can grow in a wide range of moist but well drained soils. Prefers a pH in the range 5.5 - 7.5, tolerating 4 - 8.8. Established plant are moderately drought tolerant
This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby. When removing plant remains at the end of the growing season, it is best to only remove the aerial parts of the plant, leaving the roots in the ground to decay and release their nitrogen.
