Hi Bob - yes, cutting them off right at the base is the best thing to
do. No further action need be done - just cut 'em off when you see
them. It's quite common for some varigated plants to revert.

Thanks all, been out and snipped the offending greenery.

I did notice some white fluff on the leaves. Would it be mould? I know you
can get mould killer for roses, but is it OK for other plants?
