Alphitonia excelsa

Family : Rhamnaceae

This is a medium sized tree growing to about 10 – 15 metres. It is hardy and easily adaptable to a variety of soils. It is salt tolerant, prefers full sun and can tolerate sandy soils and wind.

This is an attractive, bushy tree with distinctive thin, glossy leaves that are dark olive green on the top side and white on the under side. Crushed leaves can be used as a soap substitute as they lather well in water. Bark is greyish and smooth.

The flowers are small and appear in large clusters. These are cream coloured with a strong scent, usually appearing during the wet season. Fruits are a dry, woody capsule containing several seeds which blacken when ripe.

This tree attracts several species of birds, insects, flying foxes and moths – particularly the Giant Ghost moth and Emperor moth.
