Davidsons Plum or Mullumbimby Plum
One of the best known bush tucker plants, Davidsons Plum actually comes in three types. It is Davidsonia jerseyana, which grows in sub tropical to tropical rainforest areas that is most widely grown for the fruit.
The fruit when ripe is a purple plum colour, and is becoming very popular in restaurants around the country.
Unlike the Japanese and European plums, the fruit is acidic or sour with a strong taste.
Fruit is usually peeled before eating as the skin is a little tough. The fruit itself forms on the trunk of the tree, green at first and changing colour as it ripens.
The fruit is used to make jams, sauces, wine, ice-cream and cooked with meat dishes.
This is naturally an understory plant, so it does grow best in dappled shade. In cooler climates you will need to provide a frost free sheltered and warm position to create a micro climate for growing conditions where the plant will fruit.
In cultivation Davidsons Plum is usually pruned to a smaller size for ease of collecting the fruit. The best time to prune is in late winter.
