Hi I dont grow one but it is in my Tropical and Sub-Tropical book and thats us.
It states that it grows in Rain forest valleys and that must get a bit wet there.
The website below states that quandong grows besides streams. That is for the blue quandong,
Which one do you have, as there is a desert one that would not grow here.
Seems there are three quandong's Have a read it should help....Cheers...MM.

Here is a link that might be useful: quandong

Yes, best to use botanical names as there are quite different plants that go under the name Quandong. The plants of the genus elaeocarpus grow well in Brisbane as a rule.

Yes I have to learn and study a bit latin names! I have to look on the nursery homepage, they offered seeds and I wanted to try from seed. (But the answers are yet informatiove)

There are two VERY different kinds of "quandong". Elaeocarpus species are rainforest trees with fruits that are edible but not especially good to eat. There are some good ornamental species which would grow well in Brisbane. Some are small trees. Some are very big. Santalum species are the ones that are grown for the bush tucker industry. They are desert plants and I don't think they would like Brisbane's humidity.

There are two distinct kinds of "quandong". Elaeocarpus species are rainforest trees and should grow well in Brisbane. Some of them may even have grown on your very own patch of land before it was cleared for settlement. Some are small trees, some very big. The fruit is edible but not really worth eating. Santalum species are the ones that are grown for the bush tucker industry. They are plants of dry inland areas, and might fail in Brisbane, I think, because they wouldn't like the humid atmosphere

I can heartiy reccommend Elaeocarpus Reticulatus, the Blueberry Ash, as a great small tree for the home garden, but I gave away a magnificent potted Elaeocarpus Grandis (Blue Quandong) about 12 months ago when I realised that the mature tree would be way too big for my block. Choose (and position) wisely, and you will have the characteristics that you want in a tree without roots lifting the foundations of your house. Good luck, Artie

Brisbane people, are there Elaeocarpus being used as street trees, I think near the James Street markets and the Powerhouse? Is the proportion of red leaves a diagnostic sign? Thanks! Rose

Ah, Elaeocarpus Grandis or Blue Quondong. What a beautiful tree it is, but what a size! This tree is the only RF tree I know of - other than Hoop or Bunya Pines - that will reach its full 35-40m height in cultivation & very quickly too, I might add. Most if not all Elaeocarpus grow readily in SE Qld & are used as street trees as Rose has stated although mostly they are E Eumundii, a much smaller tree. Quondongs will handle just about any conditions well after establishment, even an occasional light frost. As for the redening of the leaves, this is not diagnostic at all its a phenomenon of the species that adds a bit of colour to the foliage. Beware of buttresing on Grandis, this can be large reaching a full 1/4 height of the tree & starts at a young age. Cam.
