Ansellia africana 'Chlorantha'

A large-sized, epiphytic, evergreen orchid with upright, cane-like pseudobulbs up to 120cm tall. Six or seven, green, leathery leaves are alternately arranged on the upper half of each pseudobulb, lasting two or more seasons. Each lance-shaped leaf is up to 40cm long and 4cm wide. Upright flowering stems measuring up to 85cm emerge from the upper nodes of mature, leafed or leafless canes and carry many sparsely-spaced, 2-3cm large, pale yellow flowers.

How to grow

Cultivation

Grow in an open, coarse bark-based orchid mix with addition of perlite and coconut chips. Provide bright light conditions, but shade from hot, direct mid-day sun. Ideal temperatures are 15°C minimum in winter and up to maximum 28 °C during summer day. Water and feed plants regularly during the growing season. Ensure that all water drains away, preventing the plant sitting too wet. Provide enough humidity by regular misting. Reduce watering and feeding in winter months and keep in a bright, sunny position. As with many orchids, they grow best when well-established and slightly pot-bound. Re-potting should be only done if the plant overgrows its container or before the potting mix starts to deteriorate - approximately once in 2-3 years. The plant should only be re-potted when the new growth appears in spring. See also indoor orchid cultivation.

Propagation

Mature plants may be divided when the plant overgrows its container. Each division should have at least 3 older pseudobulbs with a sufficient amount of stored energy and water, to support new growth and reduce stress after repotting.
