Growth—

A plant of the lowland moist tropics, found at elevations below 900 metres[1, 2]. It is found in areas where the mean annual rainfall is in the range 1,000 - 2,800 mm, and the mean annual temperature is 21 - 26°c with a mean maximum of 24 - 30°c and a mean minimum of 17 - 25°c[1]. Prefers a sunny position[3]. Succeeds in a wide range of soils[3]. The plant is common as an ornamental and gsrden escape in Malaysia, Java and New Guinea[4]. A fast-growing plant[3]. The fruit takes 10 - 12 months to mature from flowering[1].

Propagation

Seed - it has a hard seedcoat and 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 partially shaded position in a nursery seedbed. A germination rate in excess of 60% can be expected, with the seed sprouting within 8 - 12 days[3]. When the seedlings are 4 - 6cm tall, pot them up into individual containers and they should be ready to plant out 5 - 6 months later[3]. Seed can be stored for prolonged periods without loss of viability[1]. Cuttings. In Costa Rica, the plant is propagated by means of large cuttings ('epicormic shoots'). Vertical shoots of 15 cm in diameter are cut and trimmed to a length of 2.5 metres. These are laid out in the shade for a week and then stacked vertically for three weeks. Then they are planted, with the lower ends buried 50 cm deep in the soil[1]. Layering.
