Description

Davidsonia pruriens is a small to medium-sized tree that can reach heights of up to 10-15 meters. The tree is characterized by its deep purple, almost black fruits, which are roughly the size of a plum. The leaves of the tree are long, glossy, and have a hairy underside, which is where the species name "pruriens" (meaning "itchy" in Latin) comes from. The flowers are small, white, and borne in clusters.

Distribution and Habitat

This species is endemic to the rainforests of northern Queensland, Australia. It prefers high rainfall areas and is often found in the understory of dense, tropical rainforests. Davidsonia pruriens is adapted to thrive in the acidic soils typical of its native habitat.

Davidsonia pruriens is cultivated for its fruit, which is highly prized in the culinary world. The fruit has a sour taste and is rich in antioxidants, making it a popular ingredient in jams, sauces, and desserts. The cultivation of Davidsonia pruriens is challenging due to its specific habitat requirements and slow growth rate. However, there is increasing interest in commercial cultivation due to the fruit's unique flavor and nutritional properties.

In addition to its culinary uses, the Davidson's plum has been used in traditional Indigenous Australian medicine for its purported health benefits.
