Davidsonia pruriens

Davidsonia pruriens

Australia is blessed with thousands of native edible plants, yet not many people know this.

When asked to name any bush foods, most Australians will answer “kangaroo and the witchetty grub”. Yet plants made up the bulk of the traditional Aboriginal diet. Their plant knowledge was extensive and included the whereabouts, relative tastiness, time of harvest of crops of yams, edible roots and flowers, berries, fruits and nuts. They also used the small seeds of native grasses to grind and make into bread.

One fruit, native to the rainforests of Queensland and NSW, is the Davidson’s plum. It was enjoyed by Aboriginal people and is now popular with chefs around the country – particularly for jams, sauces, chutneys and even wine.

The Davidson’s plum has attractive foliage brilliant coloured fruit – dark blue/purple on the outside and a deep reddish-pink on the inside. It might resemble the shape of the European plum, but they are not closely related and the native plum is far more sour than the fruit we are used to.

There are three species of the fruit: Davidsonia jerseyana, Davidsonia johnsonii and Davidsonia pruriens. All three trees are slender, but D. pruriens, also known as Ooray or Queensland Davidson’s plum, is tallest, growing up to 12 metres high. There are a few small-scale plantations producing the fruit in New South Wales and Queensland.  D. jerseyana, native to lowland subtropical NSW, is considered endangered in the wild, but is widely cultivated. It reaches five metres high. D. johnsonii is a small tree with a spreading canopy and smooth leaves, also considered an endangered species in the wild.


Davidson’s plum prefers warmer climate zones but will tolerate cooler regions if protected from frost. Being a native rainforest tree, the plant is best grown in a sheltered, part-shaded position in the garden with ample moisture and protection from damaging winds.

Soil and Fertility

The trees are found in their native habitat across a range of soil types. However, they appear to do best in deep, friable soils with plenty of organic material. They require good irrigation (or high natural rainfall), especially during flowering and fruiting.

Flowering and Fruiting

Flowers vary in colour from red through to pink, depending on the species.  Fruits are borne either in panicles or grouped on the stem, again depending on the species. D. pruriens has larger fruit than the other species and they are produced in large clusters from the trunk or branches.

The fruit of D. jerseyana appear in early to mid-summer. Trees will bear in year 3.

D pruriens bears fruit in winter in its natural habitat but in cultivation, fruiting may extend to other seasons. This species will bear in year five or six or later.


Fruit of D. johnsonii is infertile so propagation is done by clump division, cuttings or from suckers. The other  species can be propagated by seed as well as the other methods.  Davidson’s plum can be found in some nurseries around the country including Melbourne. It can also be ordered online.

Pests and Diseases

D. jerseyana is susceptible to fruit fly infestation. There are a number of sustainable ways to combat the fruit fly. These include: regular inspection for the presence of fruit fly larvae; setting traps; collecting fruit that has fallen to the ground, put in a sealed plastic bag and leave in the sun for 3-7 days; and employing chickens to scratch around under the tree to eat the larvae.

Birds, possums and flying foxes enjoy the fruit, so netting the trees at the appropriate time is wise.  Caterpillars, moth larvae and beetles also attack flowers and fruit.


Height is controlled by pruning off the tips.  This also encourages multiple stems and fruiting.


Fruit picked just as it is beginning to turn purple will ripen readily off the tree. This will minimise the build-up of pests and prevent fruit falling to the ground to attract rodents.


In fact, Davidson’s Plum is not recommended for eating fresh but is excellent stewed, or preserved or made into jam using recipes for European plums.  Some say you should double the amount of sugar that you would use in such a recipe. The flesh can be used in savoury dishes as well.

One of the impressive things going for the Davidson’s plum is its nutrients. It has more antioxidants than the blueberry, which is known worldwide for health benefits. It also contains potassium, lutein (a compound important for eye health), vitamin E, folate, zinc, magnesium and calcium.

It is best to eat the skin as well as the flesh of the fruit as the skin contains most of the nutrients.

Another benefit of Davidson’s plum is its intense colouring which can act as a natural food colour.

Meanwhile, research is being done into its preservative properties. When tested on kangaroo meat, a product made from Davidson’s plum extended the shelf life of the meat by 21 days in chilled conditions.

  1. We have 100 Davidson Plums that have been let grow up past 10 metres. Is it possible to cut them back so they are harvestable and hope they will grow fruit within reach? How do I get them to be manageable?

    • Not too sure about this. These trees are usually pruned in the first years of growth so that fruit is harvestable. But since they grow so tall, hard pruning may not be suitable. Perhaps try on one or two trees during winter and see if they recover in spring/summer.

    • Generally the fruit will drop to the ground themselves when ripe with no damage to the fruit. They are then easily collected off the ground. You have to get to them before other animals though.

  2. We have been nurturing our Davidson plum for several years and will be putting our house in Brisbane on the market soon. I’d love to take the small tree (about 1 metre high) with us and was thinking of digging it up and putting it in a pot. Does anyone know what sort of root system they have or if they transplant well?

    • Davidson’s plum has an extensive root system which is mostly quite shallow. In transplanting any tree it is important to try to get the roots out as far as the drip line of the foliage. Since you must put it in a pot, it would be wise to choose a large one and have good potting soil ready to add to it once you have dug up the tree. It would be important to water the soil immediately to avoid damage to the roots by exposure to air. You would also need to prune the foliage a bit to compensate for the root loss of transplanting. Make sure the soil is moist, but not really wet, in the following days. But bear in mind that there is a risk to transplantation or this type of tree.

  3. how do you net a D Jerseyana when it is so tall? We lose a lot of our fruit to King parrots. – Kati

    • You have a challenge! The only thing I can suggest is providing an alternative in the form of a ‘sacrificial’ food such as apples. You may be able to get seconds or damaged apples from a fruit shop.

  4. Just read this interesting article and thought l would share our experience with Dp.
    We have Davidsonia pruriens growing and fruiting in the Yarra Valley, outside Melbourne. It is 25 years old and took about 9 years to fruit. There are fruits on it as l write.
    We also have D.jerseyana @ 22 years old and 4 metres high and D. johnsonii @ 15 years old and 2.5 metres high and yet to flower or fruit. D. jerseyana flowered for the first time in March 2017 so fingers crossed for fruit. Beautiful foliage plants.
