Family: Bignoniaceae

This native of tropical Africa is a handsome, evergreen tree, grown for its showy flowers and ornamental foliage. It makes an excellent street tree in subtropical and tropical areas and a striking specimen tree for gardens. In cooler climates, it can be grown in a pot in a warm greenhouse, but it is unlikely to flower.

Species

S. campanulata, African tulip tree or flame of the forest, grows to 20 m (65 ft) in its native habitat, but is usually about 10-15 m (33-50 ft) in cultivation. The pinnate leaves grow to 40 cm (16 in) long. The flared, funnel-form flowers are a brilliant scarlet-orange and are borne in long trusses on the tips of the branches. Flowering is from late spring through summer, with the main show usually being in mid to late summer. The flowers are followed by a pod to 20 cm (8 in) long.

Cultivation

In the greenhouse, grow in a large pot of soil-based potting compost. Even better would be to plant it in a soil bed. Ensure good light (but shade from direct strong sun), and provide a humid atmosphere. In the growing season, carry out liberal watering and liquid feed every four weeks. In winter, reduce watering. In the garden, plants need a sunny spot with moist, yet well-drained soil. Propagate from seed in spring, germinated at 21°C (70°F), from semi-ripe cuttings in warmth, or by air layering in summer.

Climate

Warmest parts of zone 10 or tropical.
