This small evergreen tree is water wise, fast growing in shade or semi-shade. The delicate mauve or white flowers occur in summer and they attract birds, carpenter bees and butterflies. The glossy dark green leaves help to create an informal screen. The wood is used to make fire by friction and it is an ideal tree for small gardens. It makes a stunning display if planted in a pot and can also serve for screening in a semi-shade area. Can be planted along a stream bank. The River Bell is a desirable garden plant as the roots are not aggressive and it is the larval host plant for the Blue Pansy butterfly. Named for James Townsend Mackay (1775-1862) Scottish horticulturist and curator of the Durban University’s botanical garden fro 1804 until his death. He was a professor, active field botanist and author.Dublin university honoured him with a LLD and a PhD in 1850 for his service to botany.
