I'll bet it's the same plants. The seeds I have are ones that came as freebies, too!
Darn, I don't have a picture of the foliage, but it definitely looks different from the other cosmos I grow. It's pretty, but not as airy as the other kind. Ha! **smacks head** Duh why do we have a database? Sheesh. Ok. I can grow Cosmos bipinnatus; the other kind is Cosmos sulphureus. But I'm still not sure why I can't get them to bloom. Maybe I'll try them again next year.
Hee hee, maybe I'll add them to my winter-sow list. Hmmm, think I'm going to have to make an actual list.
