Crossandra : Greenhouse Plants
T – tropical, minimum of 18°C (65°F)
Crossandra infundibuliformis from semi tropical rain forest in Malaysia and India is the only species normally grown and is well worth acquiring or raising from seed, which can give you a flowering plant in as little as eight months. In the right temperatures flowers are produced almost continuously and the foliage itself is an attractive shiny green. The flowers are orange-red and emerge from the bracts in such a way as to look curiously like half flowers. A very attractive variety, C. I. ‘Mona Walhed’, has salmon-pink flowers and will remain at 30 cm (1 ft) as opposed to growing up to the 60 cm (2 ft) of the species. Seed needs a high temperature of 24-26°C (75-80°F) in March to germinate well. The pest to watch out for is whitefly. Plants will respond to being cut back when they become leggy; resulting growth will either make goodor can be grown on to make a new plant.
