ZenMan, I came back to visit this thread again. I was looking at Zinnia seeds in catalog and some very high dollar, including Profusion. I notice Profusion series is called "interspecific"; what does that mean? Even though they don't readily cross with others, do they readily cross with themselves?
More specifically, I want to grow Dreamland variety. Seeds are even higher than Profusion and they are noted as being F1. In Zinnias, crossing an F1 with an F1 (same variety), will it likely produce something very similar, do you think?
Since they are dwarf, perhaps I could grow them in 2 or 3 gallon containers. Do you have any suggestions for isolating them, or do they have to be isolated by the individual flower? (I grow a lot of Zinnias for cutting flowers and don't want to cease that.) In reading this thread, I don't see you mention those (isolating flowers), or any photos as to how you actually harvest pollen and pollinate, or did I miss it? How does one know when pollen on a flower is ready?
Are there F1 hybrid Zinnias that will not produce seeds? Do the interspecifics produce seeds?
Thanks for any help.
