The striking South African Strelitzia regime, the Bird of Paradise Flower, is ideal for a greenhouse, conservatory or sun lounge which can be heated to 10°C. (50°F.) or more in winter. For brief periods, however, the temperature can drop to as low as 4°C. (40°F.) without ill effects. The common name comes, of course, from the remarkable flower which. With its brilliant orange and purple colouring, has an exotic appearance few other plants can rival. Theare borne in spring and at other times on stems up to 3 ft. tall.
Potting should be done in spring or autumn, using the John Innes No. 3 Potting Compost and 8- or 9-in. pots. Full sun should be given to the plants in the summer and plentiful supplies of water. Less water must be given in winter. In spring, summer and autumn the plants should be fed once a fortnight with liquid or soluble fertiliser. The plants flower very freely when grown in pots – they like to be pot bound and they give even better results if planted in a border. Propagation
Plants can be increased easily by division. Single crowns with roots attached should be potted first into 6-in. pots (the crowns are rather large) and later in 8 or 9-in. pots. A single crown will make a very large plant in a matter of a few years. Seeds, which will set only after hand pollination, will germinate in a temperature of about 21°C. (70°F.). but it will take three, four or perhaps more years for the plants to come into flower.
