This is white camas with us in the east, more likely mountain deathcamas out west. Deathcamas would be a good label, and would warn us right up front. Don't eat! Don't even pick! Just take pictures. Here the flowers are on a taller diffuse panicle. Out in the mountains they tend to be shorter and more compact. But it's all the same poison. Which means of course it had to be used for medicine. Although white camas was pretty much for external use in lotions and rubs.
