About Davidsonia jerseyana (F.Muell. ex F.M.Bailey) G.J.Harden & J.B.Williams
Davidsonia jerseyana, commonly called Davidson's plum or Mullumbimby plum, is a small, slender subtropical rainforest tree that can reach up to 10 metres (33 ft) in height. Its hairy compound leaves are 35–60 cm (14–24 in) long, and bear 11–17 leaflets. This species is endemic to a limited restricted area along the east coast of northern New South Wales, Australia. The tree's fruit grows directly from the trunk, and has a superficial resemblance to the European plum. D. jerseyana is classified as an endangered species. There are two additional recognized species of Davidson's plum. This tree is cultivated for its pleasantly sour fruit, which is used commercially to make jam, wine, ice cream, and sauces. It is propagated from seed, and usually begins producing a crop by its fourth year of growth. It bears large fruit crops directly from the trunk; bagging is used to protect developing fruit from sunburn and Australian king parrots. Young trees require protection from full sun and wind, and grow best with adequate soil moisture and good soil nutrition.
