Hi! I try to find what Acer is it. It's in our national botanical garden. On the board is Sieboldianum Kinugasa-yama, but definitely not according to leaves. A forgot take more pictures (I'll make more next year) but any guessing based on that? I'd like it very much, but I don't know, what have I searching for.
It's really hard to ID cultivars from photos. Certainly it's not 'Kinu gasa yama' -- that's how I have the spacing, but your version is just as likely -- but otherwise, it's probably some form of A. amoenum var. matsumurae.
100% agree. Definitely a matsumurae but virtually impossible to name to a cultivar level. I can't even think of any with a similar sounding name that look like that and could have been mixed up. Could also be a rootstock that took over if the graft died.
