Cultivation Details
A plant of the lowland tropics, where it is found at elevations up to 600 metres. It grows best in areas where annual daytime temperatures are within the range 22 - 34°c, but can tolerate 13 - 40°c[1]. It prefers a mean annual rainfall in the range 850 - 1,500mm, but tolerates 600 - 1,750mm[1]. Succeeds in full sun and in light shade[1]. Succeeds in light and medium soils of moderate or low fertility[1]. Found in the wild on sandy and rocky soils[2]. Prefers a pH in the range 5.5 - 8, tolerating 4.5 - 9[1]. Established plants are drought tolerant and able to withstand strong winds and coastal salt spray[1]. 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[3].
