in my yard right now are in the back and not noticed- pink columbines. I have three smaller plants of it nearby, one is starting to bloom for the first time and it's purple. Thinking next year I will move a few of these to the front mailbox spot- they always die back from the heat in summer, but at that point the celosia I plant in that spot will be taller, taking over. I think it would be a nice succession of color.
Closeup of the flowers that stayed short is something else.
