Whilst looking at the (Sheoaks I think). From my other post...

I noticed that some new shoots weren’t the same as the others, the area has jacarandas around so maybe these propagated from nearby trees?

Here’s the shoots near the base of a Casuarina I believe.

Any one know what these might be?













Sorry for all the iPhone photos.

Thanks in advance!

Don't know what they are, but doesn't look like jacaranda to me.
Cheers, Frank.

Chinese pistachio?

Yeah I thought these were interesting...
can’t see anything nearby that looks similar.
(Not collecting, just curious)

Toona ciliata (red cedar). It will be easier to ID once the leaves have matured

Its not a Pistachio. This has an end leaf Pistachio do not. I beleive it is Rhus tree (Toxicodendron succedaneum).
If so this tree is a toxic weed in Australia so don't handle it with out gloves. Definitely no good for bonsai.

Rhus make very nice bonsai. They used to around a lot in the old days. You don't see them much anymore. The autumn colour is unbeatable. I would make one if I could find one. True about the gloves though!


I don't think it's a rhus tree though. I was thinking tree of heavan or toona.

Agree the Autumn colour is glorious, we used to have one in the front yard years ago.
I think the reason you don’t see them around anymore:-
“The name rhus is pronounced ‘rus’ (as ‘bus’) and the botanic name, Toxicodendron, means ‘poison tree’.
It’s classified as a noxious weed in New South Wales and South Australia and those growing the plant in these states can be fined up to $2000.
It was said that people are allergic to the rhus plant but it has since been found that 98.5% of the population will develop an allergy of some kind after varying lengths of contact. Reactions vary from a rash to severe swellings of the limbs and face, sometimes producing temporary blindness”.
Sorry Mike, there are a lot of beautiful trees producing glorious Autumn colour. I don’t know why anyone would want to grow a bonsai that requires you to wear gloves to handle it safely

I agree with Mike. This looks much more like tree of heaven than any of the other s mentioned so far. Tree of heaven suckers profusely which is what we can see in the photos. It is also a very invasive species and extremely hard to kill - resistant to most herbicides. It has much larger leaves than Rhus and few branches so probably not worthwhile for bonsai.

Interesting. One of the things that led me to Toona was the leaf bases, but on some research seems tree of heaven has the same. Also lots of mention of its suckering ability which would seem likely due to the comments in the other OP's thread on Casuarina suckers in the same area. The last photo also shows a reasonably recently cut stump....

All that being said, I gotta ask :
“Why is it from heaven?”
Invasive, hard to kill (I guess that could be good) BUT not worthwhile for bonsai... mmmmm Tree from Hell!!!

Could also be Cedrela australis

Which is a synonym of Toona ciliata

Sorry to disagree Roger but my Toona / Cedrella don't seem to have those great abscission scars. I would also not expect to see a whole clump of them around Sydney - maybe further north but these have all the hallmarks of suckers from a root system. Red cedar does grow back from the base if it is damaged (down here it is usually after frost) but I have not seen them sucker freely like this. Still holding out for Tree of Heaven - Ailanthus altissima which also shows up as a weedy species for NSW as well as down here in the south.

“Why is it from heaven?”

Herbiguide says it refers to the growth habit - tall and straight with few branches ie reaching for heaven.

[/Invasive, hard to kill (I guess that could be good) BUT not worthwhile for bonsai... mmmmm Tree from Hell!!! :Pquote] interestingly, the font of all current knowledge - Wikipedia lists the derisive nicknames of "ghetto palm", "stink tree", and "tree of Hell".

Some photos of a young Toona sapling showing new seasons growth and abscission scar.

I'm still not convinced though. I think Tree of Heaven may be more likely due to what appears to be suckers. I have not seen any suckers from plants here although they do pop up pretty readily as seedlings from the large one in my garden. (Although nowhere near as large as they used to be around here!)

On a side note, I saw Shibui say on another post that they do not go deciduous for him down south. My saplings don't seem to lose their leaves, but the 10 yr old ones the neighbour planted, and the 40 odd year old one in my garden where bare for a couple of months. All coming out with beautiful reddy purple new growth which allowed timber getters to spot the large trees from some distance off.
