The message
from "Rupert" contains these words:


The invasive bit really is overdone. In ideal conditions some varieties
may
run but it does not happen overnight.
I have several so called invasive species planted about 6 years ago which
have clumped up slightly.

But when the spread does start in older clumps, it can be extremely
difficult to control

Warning heeded. If it does not take off within a few more years I will blame
you.
Whilst on the subject of invasive weeds-what was the mystery weed you
enquired about- the sempervivum looking thingy?
