December 31st, 2020

PLANT OF THE WEEK

Scientific Name: Bickinghamia celsissima
Common Name: Ivory Curl Tree
Family: Proteaceae
Etymology:Buckinghamia....after Richard Grenville, Duke of Buckingham.

celsissima....from Latin celsus, high or lofty, a reference to the habit of the plant in the wild.

Origins: Rainforests of Queensland.
Height: grows to 30 m in natural environment, but 7-8 metres in the home garden. Often used as a street tree.
Flowering: Summer to late Autumn, depending on the location, when the entire crown can be almost entirely covered with spectacular and large (30cm )  racemes of pendant white to cream sweetly perfumed flowers. Often covered in bees happily taking in the nectar and pollen.

Fruit: Wooden follicles that contain several seeds. Fresh seed germinates fairly easily, producing plants that can flower within three years. 
  • You will find that it can be grown throughout most of Australia, including as far south as Melbourne. However Buckinghamia celsissima doesn't do well in Canberra, because it hates frosts, and it won't flower in the humidity and heavy rains of the northern tropics.
  • If left to it's own devices it will go straight up like a telegraph pole and you will miss the spectacle of the flowers.
  • Tip pruning judiciously will give you a shrub as in the picture where the flowers can be observed at close quarters.
  • It can be pruned reasonably hard, but be warned, it will recover slowly.
