I have had Camassia in the garden since 2021, so not too many years. I moved it in the garden bed this Spring and it still bloomed. I was not sure what it was until it bloomed and realized I had notes for it from previous years. Read website page and see photos.
Are you going to try eating the Camassia?
Uh, I don't think so! It's too much work! I'd have to get very bored before I took the time to do that. lol
