Aglaonema
Family: Araceae
Aglaonemas are tropical perennials which are mainly cultivated as pot plants in warm greenhouses and conservatories, or as house plants. Some have extremely beautiful ornamental leaves. The exotic lily-like flowers are usually in shades of gold or green. They will tolerate medium to poor light. Most are native to Malaysia, Indonesia and the Philippines.
Species
A. commutatum and its numerous cultivars are most commonly grown. The foliage may be striped, blotched or splashed with white, cream or silver. Popular cultivars include 'Pseudobracteatum' and 'Treubii'. All grow to about 25-30 cm (10-12 in) high.
A. costatum, a spotted evergreen, is a suckering type which reaches about 20 cm (8 in). There are many shades of green and white on the leaves.
Cultivation
Aglaonemas require rich soil, good drainage, warmth, moderate light, humidity and shelter. They do not like direct sun. Keep the soil damp, but not wet, and decrease water during winter. Use a liquid fertilizer while the plant is in active growth. Propagation may be difficult and is usually successful only in a glasshouse from tip cuttings or by division.
Climate
Warm subtropics to tropics; elsewhere as an indoor plant.
