I have no clue
and I doubt I'll ever see it do that again.
We don't get spring blooms on the mums normally, but I got that one last spring, greenhouse grown, and it had buds on it that bloomed like that. I cut it back when it was done, then in the fall it exploded in solid red. We'll see if it survives the winter this year and what color it chooses next
hopefully not the crispy grey-brown
