|Distribution:||Widespread in east coast rainforests from north Queensland to Victoria. Also found on King Island.|
|Common Name:||Lilly Pilly.|
|Derivation of Name:||Acmena... After Acmene, a Greek wood nymph, presumably referring to the habitat of the genus.
smithii... After Sir J E Smith, botanist and founder of the Linnean Society.
|Conservation Status:||Not considered to be at risk in the wild|
Acmena is a genus of 15 species of which six occur in Australia. The genus was previously included in Eugenia and they are generally known as lilly pilllies. Acmena smithii is the best known member of the genus and it has been in cultivation for many years.

In nature, A.smithii is usually a medium to large tree reaching 15 - 20 metres in height. However, in cultivation it is usually a dense-foliaged, medium tree of about 8 - 10 metres high by 6 metres wide. The leaves are glossy green, lance-shaped to elliptical, about 50 -- 100 mm long by 10 - 50 mm wide and tapering to a point. The flowers are creamish/white and occur in clusters at the ends of the branches in spring and summer. They have a fluffy appearance due to the numerous long stamens but are not especially attractive, horticulturally. The flowers are followed by fleshy fruits, white to purple in colour and about 10 - 15 mm in dimeter. The fruits are edible but not particularly palatable.
This is a very hardy plant in cultivation, adapting to a range of climates from tropical to temperate and to most reasonably well drained soils. It will grow in full sun or fairly heavy shade. In an open position it usually retains foliage to near ground level. Several cultivars have become available, usually varying in growth habit:
The species is resistant to at least moderate frosts and tolerates extended dry periods once established, although it will have a better appearance if adequate water is available.
The plant responds well to pruning and can be used as a tall hedge.
The most serious pest of lilly pillies is the lilly pilly psyllid (Trioza eugeniae). This can cause disfiguring pimples on the leaves of susceptible species. Fortunately, A.smithii is rarely affected by this pest.
Propagation is usually carried out from fresh seed, either by sowing the fruits whole or after removing the flesh. Germination may be slow and spasmodic. The species can also be grown from cuttings of firm, current season's growth.
