MELBOURNE STREET TREES 51 - STERLITZIA NICOLAI

Strelitzia nicolai, commonly known as the Giant White Bird of Paradise or Wild Banana are banana-like plants with erect woody stems reaching a height of 6 m and the clumps formed can spread as far as 3.5 m.The 1.8 m long leaves are grey-green and arranged like a fan at the top of the stems, similar to Ravenala madagascariensis.

The inflorescence is composed of a dark blue bract, white sepals and a bluish-purple "tongue". The entire flower can be as much as 18 cm high by 45 cm long and is typically held just above the point where the leaf fan emerges from the stem. Flowers are followed by triangular seed capsules.

This species is one of three tree-like Strelitzia species, the other two being S. caudata and S. alba. S. nicolai is restricted to evergreen coastal forest and thicket of eastern South Africa from the Great Fish River northwards to Richards Bay. The plant prefers rich, moist soils with good drainage in full sun to part shade. The plant tolerates light frost.

Propagation is via division of clumps, offsets and from seed but note that plants require many years of growth before they begin blooming. In favourable conditions they self-seed freely, and their invasive root systems are best kept away from buildings.
