This wide dispersal sees the species given a very wide and diverse range of common names, including: umbrella cedar, pride of India, Indian lilac, Persian lilac, and Chinaberry. It Australia it is known as white cedar due to its soft general-purpose timber.
The name Melia was the Greek name given to the ash tree, which has similar foliage, and azedarach means “poisonous tree” – parts of it are toxic.
White cedar is something of a rarity among Australian native trees, as it loses its leaves in winter or early autumn. Winter deciduous trees are highly valued in landscape design as they provide all the benefits of summer shade, but allow winter light.
While Australia has an abundance of evergreen tree species and a variety of summer deciduous trees that lose their leaves in summer when water is scarce, we have few winter deciduous native trees. White cedar fits the bill beautifully, and despite a few shortcomings has some very attractive traits.
White cedar is usually a small spreading tree with a rounded canopy up to about 6 metres in height, but under the right conditions
trees can be more than 20 metres tall, with a canopy spread of 10 metres or more. They have quite dense foliage composed of dark compound leaves up to 500 milimetres long, which transition from dark green to a pale yellow in autumn.
As a winter deciduous tree they are a very popular native tree that has been widely planted as street trees and in domestic gardens, where specimens of 10-12 metres are common. The trees are often considered to be short-lived (around 20 years), but in gardens and where irrigation is available some may live for 40 years or longer.
Good specimens of white cedar have many small flowers (20 milimetre) that are white with purple/blue stripes and a wonderful, almost citrus-like scent. The fruits are about 15 milimetre in diameter and bright orange in colour. They are usually retained over winter and so the trees provide a seasonal smorgasbord – shade in summer, autumn foliage colour, orange fruits in winter, and attractive scented flowers in spring.
Many specimens are prolific in their production of fruits and seeds, which readily germinate, underscoring the weed potential of the species under the right circumstances. They can be an invasive species in some parts of Asia and Africa.
