Third time around

I love echinacea purpurea since they attract butterflies, and this is the third time I try to grow them in the garden. I have been unsuccessful with other kinds of echinacea too.  So I planted this one today, on the same spot as it have died twice before. Ok, so maybe I don't learn from previous mistakes, but I could not help myself.

In seconds the butterflies came! This is a Small Tortoiseshell.
