Aeschynanthus : Greenhouse Plants
W – warm, minimum of 13°C (55°F)
Himalayas, Thailand, Malaysia
A group of mostly trailing plants with exotic showy flowers. The calyx is usually attractive and acts as a foil to the brightly coloured flowers. In common with other members of the family they dislike water on the leaves. Carelessness in this department results in ugly scorch marks especially if the wet leaves are exposed to direct sun. They prefer to be shaded from hot sun but must have good light particularly in winter to flower well. Fluctuations in temperature should be avoided at all costs. They will be quoted as being tropical but I believe they can withstand temperatures as low as 10°C (50°F) during winter provided it is constant. Opening vents in winter and letting in draughts of cold air will make the plant drop leaves. The only remedy would then be to cut it back quite hard and keep warm and light. Most make excellent hanging baskets which will last for ages provided they are pruned back to the edge of the basket in spring every few years and fed well during summer. The tips of shoots can be taken as. Aeschynanthus lobbianus is one of the most popularly grown. It trails with fleshy leaves and tubular red flowers borne in summer. My favourite, if you can find it, is A. javanicus (A. radicans) which has the most wonderful silky tubular calyces of dark maroon. The red flower grows out from this in a most splendid way and will last for some time.
