There are salvia plants for sale all over kansas and it's straight up illegal, schedule 1. It's as illegal to have in your yard as marijuana. But little old ladies grow the shit out of it in decorative gardens still. I'd be willing to bet it's easy as hell to find, look around, ask at the nurseries. Just don't wear a band t-shirt when you go, ha ha. Include your grandmother in the question, ha ha. If all else fails, I think they sell live plants at bouncing bear botanicals.
There are hundreds of varieties of salvia (sage), but only one that will make you trip. Salvia Divinorum.
you will not find it in a nursery.
I had 2 plants I ordered online.
They weren't doing to well when I received them.
they were starting to look better after a couple weeks until I went on vacation.
