Erythrina: Greenhouse Plants
FF – frost free only
Etythrina crista-galli is the Coral Tree from Brazil. It is almost hardy if grown in a sheltered border. After it produces its spectacular red claw-shaped flowers in autumn it will die back for the winter to a tough root stock. Keep plants dry during winter and water gradually in spring as they produce buds which will develop into shoots. These shoots become 2—2.5 m (6-8 ft) tall and will need staking before they flower (watch out for the thorns). Be on guard against red spider mite. The best method of propagation is by seed soaked for 24 hours before being sown in spring. Cuttings can be taken but it is hard to find the right material. The best material would be young shoots 8 cm (3 in) long, with a small heel, pulled off the rootstock.
