Cut it to the ground and it usually flowers again in a couple of months time and it does stop it self seeding all over the place and becoming a weed.

Thanks Owdboggy. To be honest, I wouldn't mind a bit of self seeding from that particular plant! So many self-seeders don't do it in this garden. But i will cut it back now and look forward to another flush of flowers.

Just out of interest I once saw goldfinches jumping up to reach the seeds on one that hadn't been cut back - you never know your luck!

Interesting.. I do cut back most of my Geraniums after the first flush; but never the phaeums.. They are a early flowering sort and I have always thought 'leave it at that.'

Off now to take the snips to the garden!
