I hope that many donors will clarify HOW cross-pollinated donated seeds are likely to be.
For example, this case might be pollen-pure and probably is more than 90% pure:
- "I have no other plants of closely related species and I'm not aware of any in neighbors' yards"
Which is very different from this case, which might be 50-90% out-crossed:
- "This parent plant grew in a mixed of the same species, most of which were all in flower at the same time".
Plant breeders may be smart to recognize only two categories: "bagged" and "ex cultivar".
I think many seed traders appreciate knowing whether some seed started out 80-90% self pollinated (or 95 or 98%). It makes rouging out oddballs more worthwhile.
In my case, I didn't realize that many seed traders never give much thought or labeling to the pollen parent! In fact, one person told me that "OP" on her labels meant that they had been pollinated "open to the wind and sun".
