Buckinghamia celsissima is a handsome evergreen tree with a rounded canopy, it can be grown as shrub. In the tropical regions it can be a fast growing tree and in its native habitat can grow to 30m. In cooler climates, as far south as Sydney, it is quite slow growing and seldom grows more than 8m.
Mature trees have leaves are large, deep green, glossy and elliptical, with a silvery underside. In younger trees the leaves tend to be irregularly lobed. From summer to early autumn it is covered with masses of racemes of creamy white, sweetly scented saccate flowers clustered at the ends of the branches.
The Ivory Curl Flower prefers warm coastal climates, it does not tolerate frost or salt and like all PROTEACEAE it is phosphorus intolerant. Can be grown as a feature plant or part of shrubbery.
Moist well drained soils with added organic matter. Will tolerate occasional short periods of drought. A light pruning once a year after flowering will keep it tidy. Feed in spring with low phosphorus fertilizers for Australian Natives.
Named after Richard Grenville, the Duke of Buckingham. The name is from Latin celsus, high or lofty, a reference to the habit of the plant in the wild.
