David, I have some seedlings growing right now that I started from a garden variety crossed with a newer hybrid. It is a good way to start. Good practice. Also if you have Saffron, that one sets seed if another flower looks at it!!.... So, that is another one to practice with.
I do have Saffron but it makes little difference how good it sets seeds here in Nha Trang, its just to hot. This is why I am so happy and surprised that the garden variety seems to be setting seeds. I did read of a guy in Florida who had over 1000 unsuccessful crosses and then gave up for the same reason as me. Charlie says it needs to be below 70f to have success, well that happend only 2 days last year, and even then for only a few hours. Still I am not complaining, and now knowing I have half a chance its quite exiting.
