This plant can be seen growing on walls everywhere in Cornwall and the milder counties. The naturalised plants come in white red or pink (the commonest colour). I'm hoping to swamp the weeds by naturalising the red form everywhere.

I'm in zone 4a and have grown this plant for three years in a hot, dry sunny area. It requires virtually no care and blooms from early June to fall if deadheaded. If it gets floppy I cut it back and it just fills out and blooms more. This spring I tried pinching back the stems and it seems rounder and fuller. The flowers are great for cutting too. So far it seems well-behaved and has just stayed where I put it.
Update 2011 -- I have planted a few more of these, and they seem to perform well no matter where they are. The foliage always looks great, it blooms continuously, and every kind of pest seems to leave it alone. I can't figure out why you don't see this everywhere.
