I don’t know what crocuses to plant for honey bees, but, at least in my cold, damp climate of Flatrock, the big ones seem to be the better ones. They hold up better in the weather. I believe they’re called Giant Crocuses. The delicate ones wilt away quicker. From what I can tell (and I don’t know anything about crocuses), the Pickwick Crocus is the big winner in my front yard. The Jeanne d’Arc Crocus seems to hold up well too. But yup, bigger seems to be better.
