Dichelostemma ida-maia grows outdoors in my Portland, Oregon garden in a well-drained position, and has survived 18 degrees F without cover. I think it can go quite a bit colder.

I have noticed that bulbs left in the ground all summer will come up about a month sooner than than fall planted bulbs.These bulbs do not need frost protection which is part of their annual life cycle.
