I was given some seeds of this Syzygium recently. The parent plant at Kenilworth was about 5m tall and I think about 15 years old. They are native to N Qld where they may attain some height but in cultivation that usually doesn't happen. Nan and Hugh Nicholson's rain forest books - series of 5 - are excellent as reference material. Is a beautiful tree - do you really have to hedge it?

Thanks for the reply Jane.
No I don't intend to hedge it. I have planted it close to a fence and wanted something that would look good if the neighbours hacked off bits of it. I also don't want it to grow too large (powerlines overhead) so if it can be trimmed a bit, all the better. I was told by the nursery that it was reasonably fast growing, though this doesn't sound the case judging by the tree you mentioned.
I intend too coddle it, so am hoping for great things.

Tree dimensions are largely determined by environmental conditions.
Wet rainforest plants like Syzy. papy. grow much shorter in drier conditions.

Its like feeding a pig more food.
They get fatter with better conditions.
Kenilworth is a far cry from tropical north Qld, the species will tolerate the harsher conditions but the optimum time of the year for good growth maybe only 2-3 months out there. So grow is slower and due to less humidity-lower rainfall and colder conditions the height will be shorter.

Ive seen very large growing rainforest species put to a hedge situation.
Syzygium malaccence-Syzy. tierneyanum-Xanthostemon chrysanthus- and many others.

Give it a go.
You wont end up with the hedge being 80% trunk!!

Thanks for the good advice Kris!

Hello! I live in Florida, Zone 9B, and am very interested in cultivating the Syzygium papyraceum. Would anyone be interested in trading seeds for any species here? I am a licensed plant broker and am able to obtain very many different and unusual species--some endemic to this area and others entirely foreign. Thank you very much for whatever help you can give me. Please email to rareplantbroker@yahoo.com
