I understand that it's courteous to indicate on a traded seed packet that the blooms were not bagged and insects had their way with the plants. I never assume that traded seed is maintained fussily in total purity unless someone says so specifically (or it came from Jonna).
But I'll go back to my first post on this thread: I wish there was an easy and agreed-upon way to indicate ABOUT how true-to-the-parent-variety the seed is likely to be.
- from a commercial packet
- some thought given to isolation but no guarantees
- grown in a mixed bed so expect 50% cross-pollination
All three are valuable, and any petunia seed I save is in the third category (but I do grow some in pots so I can move them to opposite ends of the deck, so I can encourage distinct colors).
