The Tuckeroo first came to my attention a number of years ago, when an enthusiastic gardener friend of mine was telling me about a stand of Tuckeroos that had been identified at Tuggerah, and horrors, the land on which they stood belonged to one of the power stations and they wanted to bulldoze the lot. Iím not sure what the outcome of that story was but the name Tuckeroo has stayed with me ever since. Confession time: I wasnít that enamoured of native Australian trees at that time, but hankered after luscious exotics. Now Tuckeroos and I have become good friends. Iíve noticed them growing in Surry Hills, Sydney and proving to be attractive, tough street tree, coping in a tiny patch of dirt in a sea of concrete on a busy road. It was the fruit which first caught my eye. Rather large three sided orange berries, in bunches all over the tips of the branches.


I saw them again on a recent trip to Queensland and realized again how beautiful they are. They are obviously much more at home in the sub tropics and grow into very handsome trees, still the same inconspicuous flowers but such gorgeous orange fruits!

I noticed that they are being utilized as a tough evergreen tree in all sorts of places in Brisbane, and also alongside the carpark at the Sunshine Coast airport. I do like it when I meet up with old friends, both human and plants.


The shortish trunk is rather handsome too being pale to dark grey with raised horizontal lines.


The flowers are relatively inconspicuous, OK letís be honest, if you werenít looking for them you wouldnít notice them at all, as they are very tiny, and a pale creamy green. They are about 5mm in diameter occurring on axillary branched panicles. The sepals are round, petals small, with about 8 to 10 stamens up to 5mm long. The flowers appear in winter; but the ensuing 3 lobed fruits are the true attraction.


They are a large, three-lobed capsule, green to begin with and then turning a bright orange - very showy indeed. They split when mature to reveal black or dark brown seeds nearly covered by a bright red aril. The trees are most beautiful in late winter to early spring when the fruits ripen.


The foliage is dark green, thick and rather leathery. The leaves are alternate pinnate compound, with 2-6 pairs of leaflets and about 7Ė10 cm long. Each leaflet is a rather odd obvate shape with a blunt or notched apex, dark glossy green on top and a lighter green beneath. The veins are distinct on both the top and bottom of the leaves.

Tuckeroos deserve to be grown more readily as a street tree, anything to get rid of all the plane trees really. They are an evergreen, tough hardy tree that can adapt to difficult sites and even pollution laden air. They can grow up to about 8 metres tall with a similar width and have a full rounded crown. While they appreciate full sun they cope quite well with partial sunlight, or even quite a degree of shade. They can cope with many different soil conditions so are quite adaptable. The only thing they dislike is to have their roots remaining in water for any length of time. They are tolerant of coast exposure and salt spray too. They would make a good nurse tree for people attempting to regenerate bush land. They are frost tolerant but probably prefer the warmer northern coastal regions along the east coast of Australia.

The foliage and flowers are food for a number of Australian caterpillars, including :
