Elaeocarpus angustifolius is largely a tree of tropical rain forests, but some southern Australian accessions are being cultivated in temperate areas, often under the synonym E. grandis. It is popular as a garden tree in Australia, where it is valued for its evergreen foliage, turning scarlet as it senesces, and abundant marble-sized blue fruits. It is in cultivation at the San Francisco Botanical Garden, but mature specimens have not been located elsewhere in our area. At Cistus Nursery seedlings are being tested for hardiness and evaluated for leaf-colour qualities (S. Hogan, pers. comm. 2007).
