Cultivation Details
A plant of the 'Caatinga' dry forest region of northeast Brazil. The climate is hot and dry, there are usually 6 to 11 months without rain each year. The mean annual rainfall varies from 250 - 1,000mm, and the mean annual temperature is from 24 - 26°c. Requires a sunny position[1]. Found in the wild mainly in alkaline soils[1]. A pioneer species, it can rapidly invade pasture land within its native range and is considered to be a weed by cattle ranchers[1]. A fast-growing plant[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, unless sown as soon as it is ripe and still moist, may benefit from scarification before sowing 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. Sow the seed in a sunny position in a nursery seedbed. A high germination rate can be expected, with the seed sprouting within 14 - 28 days[1].
