I'm with you on the catnip! I have it everywhere. Same with horehound!
But I have always just planted seeds, chaff and all if they are small seeds that are hard to separate. Of course I never traded seeds before, just given them away. I guess if I'm trading I should do like ou do Rick, and save the clean ones for trading.
Seriously, on Verbena Bonasaris, I have never collected seeds so when I just did to give someone, I had no idea what the seeds looked like!
