I have a lot of them and they are all growing together in one area. That is why I said if you want a certain color bloom I will have to wait until they are blooming and put your name on the pad.
I planted them in a area that I do not plan to ever touch again. I sat on a bunch of them one summer and I swear I did not think I was ever going to be able to sit on my behind again in life. So they are all in a safe spot by themselves.
