Ran across this striking perennial earlier this week after loading some dry cows to go to town. Apparently common, I have never seen Silverleaf Nightshade, so I went back this morning to photograph it. Related to the tomato, potato and many other garden vegetables, it is poisonous with narcotic properties. And like many nightshades, natives prepared concoctions with the fruit to address headaches, sore throats, etc. Also the root was chewed before sucking rattlesnake venom from a bite. I continue to wonder how the natives knew when to pick the berries and how much of their preparations to ingest. All in the realm of the medicine keepers, I suspect it was not just trial and error.
