I t ' s a F R E A K o f n a t u r e . . . . I think it's still purdy (poor thing).

Sometimes it is good to get outside the box. Rock on, little daisy!

It's growing a mustache ;-)

I'm no expert, but I had some roses do that and was told by a rosarian it is because of too much nitrogen in the soil.

Maybe it's like having a 6th finger or toe? ;-)

Your picture made me remember a flower I saw at a friends house. It looked like two flowers that were conjoined in the middle. The result was the center being the shape of a heart. I didn't have my camera with me. It frustrates me that I never went back to take a picture.

I hope you saved your seeds. You might want to see if that can be reproduced.

I don't know if it's anything too rare. I remember I had daisies that had a few flowers like that a couple of years ago.
