    I have these two shirasawanum from seeds taken on a shirasawanum 'Autumn Moon'. They are quite different from each other, see : Autumn colors 2020 - Maples

    I suspect the taller one, with smaller leaves, is a cross between A. shirasawanum and A. palmatum, look at the buds (one square is 0.5 cm) :

    For a comparison, buds on the 'Autumn Moon' :

    I posted several photos of these two in other threads.

    Here they were in June 2020. Two brothers but a bit different, from seeds taken on the same parent tree, Acer shirasawanum 'Autumn Moon' :

    Photos of the leaves taken today :

    The smaller one looks more like a shirasawanum : brown-greyish bark, large leaves with 11 lobes on average, leaves a bit larger than on 'A.Moon' :

    The one that I suspect is a cross between shir. and palm./ amoenum has smaller leaves with an average of 7 lobes and the bark of 2-3 year-old branches are reddish :

    They both get the same amount of dappled shade in late afternoon, and were both repotted in the same medium each time, at the same time.

    A photo to compare the leaves, and one of the parent tree (which has been in almost full shade for the past 2 years) :

    They're both quite pretty! The 11-lobed one does indeed look like shirasawanum, but who knows? :) It is curious how differently seedlings come out, even on the same branch. Clearly this is sometimes down to hybridization, but sometimes there seems to be a facture of mutability: not for nothing A. palmatum was also called Acer polymorphum! -E

    It's just come to my mind the tall one with smaller leaves could be called Acer 'Shirpal'. Sounds exotic enough to be a hit on E-Bay, doesn't it ?

    Om shanti om... ;0)

    Vibrant colours against a black backdrop :

    Woww amazing…leaf perfect!

    In contrast I have found 2021 has not been a great year for Japonicum nor shirasawanum.. Jordan, Vitifolium, Meigetsu and Aureum..but Attaryi and Aconitifolium has been good..very strange
