Ok,I had thought this was blanketflower (gaillardia), but my sister was out visiting and said it couldn't be since it has daisylike seeds rather than the pom pom like seed heads of gaillardia. I have several plants and they range in color from plain yellow flowers, to yellow and maroon flowers, to all maroon flowers.All have a dark center. The flowers are all large (about 5 inches across) and are very pretty. My best guess is some kind of black eyed susan or rudbeckia but I haven't been able to see any picture id's in anything but plain yellow. I also have another similar flower that I will post next that looks like a black eyed susan with double flowers.
I believe this is the rudbeckia called "Indian Summer". Save the seeds, whatever it's called, and I'll trade you something for them!
I think these and the double flowers are all forms of rudbeckia hirta ... just different cultivars. I think they cross pollinate and will come back with even different color combos. Burpee has a double called 'Goldilocks' or something like that. I've collected seeds from doubles but about only about a third of the seedlings will have double flowers.
I grew the rudbeckia Indian Summer Daisy last year from seed. Thought they were suppose to be solid yellow (you probably got either the seeds or plants from me) and I figured that was what the solid yellow ones I've got were. Just didn't realize they would cross polinate into such beautiful and vivid color combinations. I've got some of the yellow and gold ones but not the really dark maroonish ones like you have so I guess ours have just cross polinated differently but all must be cultivars from the original planting. PS - thought I had already identified your gloriosa daisy for you last week. I think you got those from me as well.
Kat7, I got your message and tried to e-mail you back with the rply button, but I keep getting your mail returned to me. E-mail me direct at email@example.com with you address and I'll send you a SASE for the seeds.
