I guess nothing is safe. Crocuses are a delicacy here too - bulbs and tops. As for daylilies, my house came with the orange ditch lilies and as nice as they are, they spread and orange doesn't really go with those violetish-white hosta flowers that bloom at the same time. I tried to get something interested in them, even left some tubers above ground but no takers. I read they are edible for humans. Maybe I should try.
