North American native blue salvia
Offering seeds for postage. This is not S. divinornum. Is probably this https://www.fs.fed.us/wildflowers/plant-of-the-week/salvia_azurea.shtml Probably isn't a very good sage for cooking either, as the leaves are not very fragrant. Grows about 5 ft tall, and is still in bloom in Missouri at this time, early November. As the link says, it attracts bees and butterflies. It can be grown sort of like a light hedge, but is probably best cut back each spring to encourage thicker growth if you want to use it that way. Otherwise, a low maintenance plant.
