I usually say “locally adapted crops.” People get it.
I usually lead in with “saving your own seeds.” Thriftiness and self-sufficiency are popular here, so a lot of people like the idea of not being dependent on buying seeds every year. All they need to be told is that they can, basically given permission to try it, and sometimes also given a little bit of encouragement about how easy it can be to learn, with perhaps a little bit of information about the basics of how to do it.
Some people are resistant because it sounds like too much work or bother, and “buying seeds is cheap.” (I hear this all the time.) I usually agree, and then say, “But the seeds you save can be better than anything you can buy. If you save your own seeds every year, your plants will probably take less work to take care of every year, and they’ll start to do better with less work from you.”
Then even the people who don’t want to save seeds because it sounds like a bother get interested. They can see that it may be a path to less bother in the long-term, which is something most people are interested in.
So a usual conversation might go like this:
I say I like gardening.
If the other person does, too: I say I really like saving my own seeds.
If the other person saves seeds, too: I ask what sort of neat things they’ve grown from their own seeds. We have fun talking about garden adventures!
If the other person doesn’t save seeds: I tell them saving seeds is nifty because it’s free, and you’ll almost always get something as good or better than what you grow before. A lot of people are intrigued by this.
If they say buying seeds is cheap, or less bother: I say plants grown from saved seeds tend to be better than anything you can buy, because the plants will need less work from the gardener every year. A lot of people who consider “too much bother” a barrier find that idea interesting.
If they still aren’t interested: Okay, no problem!
Maybe someday they’ll be interested. Maybe someday they won’t. If they never are, they’re still growing food locally, probably with fewer industrial pesticides and fertilizers than a huge monoculture farm would, plus fewer fossil fuels burned to transport the food, so it’s still an environmental win. Plus they’re having fun, and learning gardening skills, and probably eating a little bit more healthily as a result. All wins!
I personally think it’s perfectly fine if people want to keep crops inbred. Or clone them. If they’ve got something specific they love just as it is, that’s fine! I usually just focus on giving people permission to save seeds and not worry about possible crossing. They can decide if they want genetic diversity from there. It’s fine!
Maybe a title like this would be useful at some point?
Save Your Own Seeds: Growing Locally Adapted Crops
I would totally pick up something like that, and I bet a lot of beginning gardeners would.
