Unlike Nick, I'm not surprised by reversion to self-colour. In time,
several of the variegated forms send out plain shoots; because these
are more efficient at the chlorophyll game, they will eventually
overpower the rest if you leave them to it. You have to watch for
these green shoots, and if your variety sends them out you should
tear them (not cut them) off as soon as you can see what they are.
The worst offender for me was a clone of Goldheart taken as a cutting
from a friend's garden: all three plants I raised were guilty. Aspect
is important, too: too much light and the variegation diminishes.

Well, I said that I hadn't heard, but evidently I hadn't been paying
attention :-)

I am no ivy lover, but I find them the sort of wild plant that isn't
much hassle and attractive in context, though I agree that they are
a real problem if there is anything that they can get between and
lever apart. As weeds, I remove them when they get in the way, and
otherwise let them do their thing - unlike nettles etc., ignoring
them isn't inviting an invasion in future years.
