Here is a leaf that has puzzled many a horticultural expert over the time i have had these . I have had 4 Qualified Nursery men and women give different answers as to the species .The leaf in question is the large golden Elm 1 /Chinese lace bark elm
2/ Chinese rough bark elm
3/ Japanese gray bark elm - Zelkova - Bonsai
4/ Japanese gray bark elm - Zelkova - Tree
5/ American Horn Beam
6/ Ulmus Procera English elm ?
7/ Ulmus Procera English elm?
8/ Unknown Golden Elm for I.D - Natural sized leaf
9/10- Unknown golden elm for I.D - Bonsai Trainer
9/10- Unknown roots stock from the 3 m high tree
The 2 names i can recall from the Nurseries were
1/ Ulmus Procera "Louis Van Houtte
2/ Ulmus Glabra "Lutenscens"

I appreciate any assistance with the correct I.D.

Hi Ian
I can't help but do you know what number 11 is ? I found one of these trees at Caboolture and took some cuttings from it - most have failed. It has a distinctive zig zag in the branches and leaf type. Would love to know what it is.

The largest one definitely looks like Ulmus glabra 'Lutescens' to me.

*EDIT* The last one on the right looks like regular Ulmus parvifolia but when it is elongated as often happens during suckering or vigorous growth.

Hi Bougy Fan, its the branch and leaf configuration of root stock on the one Goldem Elm not severed off, a 3m high tree .It does look very similar to a Chinese elm in shape and size however the bud and leaf stalk is distinctly brown not green like Chinese Elms i have here .

Hi Joel , o.k ? could or is Ulmus Glabra grafted onto Ulmus Parvifolia , check out the last pic in the "Carved Elm Trunk" topic and it shows the golden leaf growing with this rootstock .Maybe this might help with the I.D .

Cheers Alpine

hi there , without a doubt this is Ulmus glabra " lutescens " ( golden wych elm ) large leaves that hold their golden colour from spring to autumn , ulmus louis van houtte starts yellow but often reverts back to green over the growing season , also has smaller leaves than lutescens . it is most likely grafted on to the species glabra which do sucker like nobodys business .

Hi eyleene , i think you have nailed it for sure . The leaves do hold their colour on the majority of these trunks . Some do revert to green , but one must remember these 30 odd trunks were from a batch of 100 or so bulk purchased grafted tree's purchased for the Winery as landscape tree's . The trunks which have mixed colours could have a sucker mixed in just below or around the graft mark . With the reduction in leaf size due to Bonsai -ing they blend in very well and the grafts are top quality i can barely see the fused area .

Many thanks .Cheers Alpineart
