Cultivation Details
Young seedlings grow well in the dappled shade of the forest, but they become more light-demanding as they grow older[1]. Species in this genus are mainly found in the wild growing in sany soils and on limestone escarpments[2]. In cultivation they are likely to do well in a fertile, loam soil and a position in full sun[2]. 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].
Propagation
Like many species within the family Fabaceae, once they have been dried for storage the seeds of this species may benefit from scarification before sowing in order to speed up germination. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!) and then soaking them for 12 - 24 hours in warm water. By this time they should have imbibed moisture and swollen - if they have not, then carefully make a nick in the seedcoat (being careful not to damage the embryo) and soak for a further 12 hours before sowing[PFAF]. Softwood cuttings of many species, especially if taken from younger plants, will root in a well-drained, sandy medium in a closed case with bottom heat[2].
