Hi Jo Ann,
I'm glad you like the star-tipped hybrids. I am crossing my star-tipped and Razzle Dazzle zinnias with several other zinnia types that I have, like my "toothy" zinnias, which were primarily created by inter-crossing Whirligigs that had some "toothy-petal" tendencies. These are examples of my current toothy-petaled zinnias.
Like most of the pictures here on ATP, you can click on them to see a larger version and, if you wish, hit the F11 key to see a "full screen" version. I left an "Idea" on that subject a few days ago.
That first toothy appears to have a white backside to its petals, and I am very interested in that possibility. I have no idea what the results of those "toothy X star-tipped" crosses will look like, but I am looking forward to finding out this Winter, because I plan to grow a few of those crosses indoors (not easy to do). I hope that my indoor zinnia project will produce a supply of interesting zinnias to grow outside next Spring.
ZM
