There are a variety of common names including Red ivory wood, Purple ivory and Pink ivory. They originate from Africa and Asia and have attractive small ovate fruits which are a source of food for birds.
The bark appearance when developed has a rough texture, flaking and slightly corky but it smooth on young trees. The new shoots are reddish in colour and the autumn colour is good. They are flowering trees that have star like flowers, formed in clusters on stalks, then followed by the small fruit.
