Inspired by this tragically shortened reddit thread about a guy who travels around collecting wild seeds to sell to native plant nurseries, conservationists, and plant biologists. If you've got a patch of wild lands with some rare plants growing on it, you could check in with your local nurseries and universities and find out what they're looking for right now. With luck, you might already have something growing that they're looking for.
Charles Martin from the Alcade Center here in NM is good about letting those of us on his email list who is looking for what and opportunities he knows of. It can be lemon balm or goats heads(horny goat weed), etc.
Once or twice a year the Alcade Center will open its doors and we can go and collect seed and cuttings from their plantings. Many of these are native plants Charles wants to share.
Times are tough, I'm needing another income. This sounds like something I would be very interested in doing. Anyone have suggestions as to who might be some potential buyers?
I sold native plant seed for many years.First worked with a company and paid hourly.Later worked for a wholesale/mailorder company.The best money is in the obscure,alpine,hard to identify stuff.I wanted to gain traditional gathering experience with food plants so I tended to pick those at best making $40hr but most often $15.It requires an expensive learning curve but once u have your sites it pays better.
There is nothing permanent in a culture dependent on such temporaries as civilization.
