Are you positive it's a dandelion? Just guessing, but multiple
heads with dandelion-like flowers could be a type of hawkweed:

Yep, I'm absolutely positive it's a dandelion. I wish I had a scanner so I
could show you how odd they are. I dried some of them. The stem was
actually about an inch wide on the biggest one -- sort of wide and flat like
a lot of stems joined side by side. Then it was capped with all these heads
all jumbled together, not on individual stems. They were so tightly packed
sometimes, that I couldn't get a good count.

Giselle (same year but in a slightly different area I also got a zinnia with
two heads, a black-eyed susan with two and a co-joined cherry.
