I have this Maple seedling that I found in a local woodland and I grew it in a pot for a couple of years and it sulked so planted it out last year. This year it has leafed out with an unusual subtle leaf colour, every leaf. It was plain green last year.

Would this be considered variegation?

Has anyone seen this sort of thing before?

An I right thinking this is a Norway Maple?

The impossible question lol, will it stay this way?

Thanks

Denis
