Does anyone have any idea? I have some that are probably 5 years old. I'll probably wintersow a jug or two of them anyway (nothing to lose...) and sow heavily, but I was wondering about the likelihood of seeing sprouts. I have had success with some that were several years old but never tried any this old.

Karen, here is a good chart to have handy. Zinnias are at the bottom.

Hope this helps.

Thanks, Chris. I'll sow a jug soon, sow heavily, and see what happens.
