'hayley',

I agree, it can get somewhat rampant. Just try and restrict it with the
use of a spade, if you can. The suckers are not very deep and you
should be able to keep it in bounds by the prudent pruning of its roots.

I've one of these in my (heavy clay) garden - it has pom pom type
yellow
flowers about an inch across. It is going mad - sending roots and
stalks out
everywhere but I've never heard it described as a problem - is it just
me?
And what should I do? I'd rather not dig it all up as it blocks out
the
neighbours conservatory which would otherwise overlook us but do not
want it
to take over the whole border - is there any kind of weed killer that
will
just kill bits of it without killing the whole plant? The suckers seem
to go
as deep as I can dig
