I really didn't pay much attention to this plant for a couple of years. Then by some chance I really DID pay attention and started to appreciate it's quiet beauty. Some material I read about it was negative .. invasive problems etc ... but I don't find that at all with this little beauty. It has been so well behaved in its spot .. blooms almost the whole season .. Spring to Fall. I haven't seen it offered at the garden centers this year .. so I am glad I picked it up when I did ! Nice one !
