So know if someone wants to plant blue morning glory, do you have to register like you do when you need to buy cold medicine?
Well..if you do...I’m in a load of trouble...have large amounts of MG in my yard (domesticated, not rampant one)
In the 1980s, “Chinese Morning Glory seeds” were not being bought to be grown, apparently — but the seeds have to be cleaned by blanching, in order to remove the various pesticides, fungicides and such that are applied to keep the seeds from going bad on the shelf.
Thompson and Morgan seeds (out of the UK) sell peyote cactus seeds, perhaps other stuff, but they aren’t legally obtainable (yet) in the US.
There are other, wild-growing options, but as all “vision quest” types of plants are poisonous if you get enough, I’m done posting about it. :’) In most parts of the lower 48, there are half a dozen plants in the vicinity (usually within feet or yards of the back door) which will either gitcha high, or kill ya, or both, depending on how they’re used. Just to be tricky, one of them looks exactly like a genus of harmless plants which has dozens of species growing wild. :’o
