About

Acronychia acidula, commonly known as lemon aspen or lemon wood, is a species of small to medium-sized rainforest tree that is endemic to Queensland. It has simple, elliptical leaves, small groups of flowers in leaf axils and more or less spherical fruit. The aromatic and acidic fruit is harvested as a bushfood.

How to grow it

The tree is grown in small-scale commercial bushfood orchards on the east coast of Australia from North Queensland to northern New South Wales. The tree is quick-growing and requires regular pruning to maintain a practical harvesting height. It has a moderate crop yield, and bears in four years from seedlings. It prefers well-drained and fertile clay loam soils, with a sunny aspect and extra moisture when young.

Where it grows

Lemon aspen grows in rainforest at altitudes of up to 1,000 m (3,300 ft) from the Atherton Tableland to the Eungella Range in Queensland.

Uses

Lemon aspen fruit has a grapefruit and lime-like flavor, and is popular in beverages, sauces and confectionery. The fruit has high antioxidant activity.
