where frosts are not severe. Numerous cultivars have been selected for variations in leaf colour and pattern, often variegated with creamy-white to yellow edges or centres, and dwarf forms. The cultivar 'Gold Capella' has gained the Royal Horticultural Society's Award of Garden Merit. Poisoning There is no evidence that this species is responsible for poisonings. It is widely used in animal enclosures in zoos and pet enclosures. Care The plant prefers higher light if possible, but can adapt to a wide variety of light levels. As a tropical plant it likes moisture (and humidity), but avoid letting the plant sit in water after you water it. It likes to be moist but not wet so just let the soil dry out between waterings. Aerial roots Under the right conditions, this plant will produce aerial roots that, when they reach the ground, will convert to fully functional roots. They give the plant an unusual and interesting appearance. Three conditions must be maintained for the plant to produce them: a high growth rate, insufficient trunk roots (the plant is root bound or these roots are pruned) and constant, very high humidity.
