Cultivation

It is commonly grown in mild to warm climates as a decorative tree in larger gardens and, when mature, it has red spikes of flowers with up to 20 racemes which develop in summer or early autumn. Propagation is by seed or cuttings. It prefers well-drained soil and only needs occasional watering and feeding to thrive. It is, however, an aggressive plant and its roots can dominate surrounding soil. In some areas (e.g.,
