Hardy Geranium invasion!!

I think I have this one - yes, it does spread doesn't it. Nice tho - helps keep the weeds at bay, except there's couch grass coming up through the one clump now - and that IS a menace!! I've also got a blue one which is really beautiful at this time of year, but boy does that one spread! It used to be contained between two large shrubs, but I removed one shrub last year and since then the blue geranium has been trying to make a break for freedom!

Sid - I culled a bit but felt guilty so I potted them up!
Why!!??

To give them as gifts to people you don't like??!! LOL
