General Discussion & Chat: Not sure where to ask this question, 1 by Windy

I have some gaillardia, not sure which type. This year the one plant went a little goofey and started setting flowers on top of flowers. The new flower stems come right out of the used flower. It isn't from wet seed heads as they are there when the parent flower is still in bloom. I didn't think the flowers would mature, but they have and have long stems also.
What caused this? Is this some sort of mutation, or is it a disease thing?
