    A hybrid between Acer griseum and acer pseudoplatanus. This tree has large trifolate leaves like the father with handsome purple undersides as shown in the third pic. For the bark I have read contradictory statements, some saying that it will flake, some saying the contrary. The fourth pic shows the bark of my young plant, it does not look like griseum to me. It is supposed to grows to about 6-8 m.
    I find it original and different from any other maple I know, worth the addition to any garden. I am counting on spectacular Fall colors.
    I do not know who selected this hybrid which seems available from both sides of the Atlantic. If anybody knows, please pitch in.
    Mine comes from Esveld.

    Gomero, I often wonder how one can be sure of the parentage of this one. The bark looks more like triflorum, but who knows what the inter-section combination would do?

    I was under the impression it was selected at Esveld, but can't find the reference, if indeed I read it.

    Thanks for the pictures, I look forward to planting this one day.

    I'd be extremely sceptical about the claimed parentage for this, and won't accept it without conclusive DNA testing.

    For what it's worth, the foliage looks very like Acer heldreichii.

    Hi Michael,

    The seller claims that DNA tests have confirmed parentage.

    On the other hand I think that leaves are quite distinct from A. heldreichii . They are much more incised, all the way to the base and the central lobe is narrower and longer, just like over sized A. griseum leaves. The lateral lobes are at 90° with respect to the central lobe while for A. heldreichii they are at about 45°.
    Also A. heldreichii is most often five-lobed while the hybrid in this post is almost always three-lobed (at least my tree). Here is a link to A. heldreichii leaves.

    Fascinating! The first time a maple flowers is always an event! (Well, I think so anyway: my A. pictum is flowering for the first time this year).

    Alex, is there any chance you can get a good close up of these flowers?

    I bought a young graft of this early this year when I visited Esveld, but the graft isn't well enough healed to put in the ground yet. Perhaps this fall.

    Hard to tell from the pics but it would seem that the individual flowers are like pseudoplatanus while the inflorescence looks more like griseum
    I have not taken a look at mine, I will check it out tomorrow.
