I have a little project going and not sure if I will succeed. Gathered seeds of miniature zinnias that I grew by mailbox from swapped seeds..this second generation is growing in pots on the porch. Still a few weeks away from flowering. My zone stays warm thru Christmas with just a few cold snaps so my goal is to bring them in at night when we get frost warnings then move them back into the sun during day. This way I can have blooms through winter. Much better than mums that blooms a short while. Lets see how it goes.
