Acer p. 'Beni Schichihenge' question
I have a 'Beni Schichihenge' that has been in about three years and is doing well. When it leafs out, which it is doing right now, it produces some leaf clusters that are solid green, rather than variegated. The vast majority of the leaves are what one expects on a B.S., with just a few solid green. Is the tree 'reverting' in the sense that variegated plants of other genera do when they are unsound? Do I need to be vigilant about pulling the green portions off? Aesthetically it does not look bad as there are so few of them, but if I were to let that happen with a variegated Abelia or a Lonicera, for example, pretty soon the entire plant would be solid green. It is in partial shade, if that matters, and at this time of year much more shade than in summer.
Thanks for any insights!
