The first photo is a specimen in my garden with (what I assumed was typical) uniformly sized and colored leaves. The second and third photos are from another specimen acquired today from a local nursery. Are these variations in leaf size and color typical of Mikawa Yatsubusa? Or is it due to stress, reversion, or some other problem? Thanks .
Good morning @OHGrow and welcome tonthe maples forum. Looking at your Mikawa Yatsubusa I would not be concerned at all. What you see there is the older leaves plus the new leaves that are always brighter and obviously smaller coming through. IMO it is growing well.
