Cultivation Details

HabitAnnual/Perennial
Growth—

A plant of lowland areas in the tropics, where it can be found wild at elevations up to 200 metres[1]. In Indonesia it is cultivated at alevations around 1,650 metres because it is attacked by pests at lower elevations[1]. The plant grows wild in areas where the mean annual rainfall is in the range 1,000 - 1,500mm[1]. Indigo species generally grow best in a sunny position, preferring a well-drained but moist soil[2]. Many of the species will also succeed in drier conditions and in poor soils. We have seen no specific information for this species, but most members of the genus have 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.

Propagation

Seed - it has a hard seedcoat and may benefit from scarification before sowing in order 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.
