Cultivation Details
Grows best in a sunny position[1]. Prefers a fertile, alluvial soil, especially if sandy[1]. Established plants are drought tolerant[1]. The plant self-sows very freely in open areas, to the extent that it is considered a weed of pastures by cattle ranchers[1]. A fairly fast-growing plant when young, easily reaching a height of 2 metres within 2 years from seed[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[2].
Propagation
Seed - it has a hard seedcoat and benefits from scarification before sowing to speed up and improve 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. Sow the treated seed in a sunny position in a nursery seedbed. A low germination rate can be expected if the seed is not treated, with the seed sprouting within 14 - 21 days[1].
