Cultivation Details
Found in a wide range of habitats from the tropics to the sub-tropics and from dry climates to moist ones. At least some forms of the plant can tolerate moderate frost[1]. Grows best in a sunny position, but also tolerates partial shade[1]. Succeeds on a wide range of soils[1]. Tolerant of dry conditions[1].
Propagation
Seed - sow the seeds in a container onto the surface of the compost, pressing them down lightly. Place the container in a shady spot and water well, being careful not to wash the seed away. Germination should take place after a week. Transplant the seedlings into individual containers when they are large enough to handle and they will be ready to plant out when they reach a height of 20cm[1]. The seeds have water-absorbent hairs[1]. Cuttings around 12cm long. The ideal rooting temperature is between 15 - 25°c. Water twice a week. After rooting, transplant the cuttings in a good soil mixture and place them in 60% shade until established[1].
