Hi All Not sure if this is the right section in the forum. A colleague quizzed me about the lack of chlorophyll on the margins of these Buxus leaves. I suspect it's a type of virus that's creating the variegation. Your thoughts and opinions are warmly welcomed.
A variant type with yellowish or tan leaf margins is frequent among seed raised Buxus sempervirens. Purple Japanese barberry also produces a percentage of gold edged plants when grown from seed, hence the named selection 'Golden Ring'.
OR, see this thread for other possibilities, where the marginal colouring disappears with time or treatment: My boxwoods have a yellow leaf edge. Deficiency?. The marginal colouring did disappear on the ones I mentioned in that thread.
