'Tete a tete' and others easily split from their and can do really well after replanting. We just love them!
It's been the best ever year, here, for these little chaps, as last year I took all the pots we'd bought, and planted them individually in a new bed - they're everywhere now, and I really didn't expect to see so many thriving!
We've also got some 'new' ones called 'Topolino' to plant out soon...
