Species

C. callistegioides grows quickly and densely, producing a profusion of pale violet flowers, with darker striping in the throats, in summer. It will grow 10 m (33 ft) in a season in warm conditions.

Cultivation

Grow in a warm greenhouse or conservatory in frost-prone climates. Use large pots or tubs filled with soil-based potting compost. Ensure maximum light, shade from direct sun and a humid atmosphere. Support of some kind will be needed for the stems. Thin out some of the oldest growth at the end of the flowering season. In frost-free climates grow outdoors in a sunny spot with well-drained, fertile soil. Propagate from semi-ripe cuttings in summer, or from seed in spring. Provide bottom heat for both.
