I was reading up on these because I have several of them. I just found out they are poisonous. I knew it was a house plant, not a garden onion, but I didnât know it was poison. Also found out they are good for bee stings, removing splinters, and can be used for burns much the same as aloe vera. I've read that they can be grown outdoors in warm areas, such as southern CA. I'm wondering if they would survive a winter here in zone 7/8. I might put one out next winter and find out. Does anyone have any more interesting information about them?
