White Petticoat is recently registered, but I consider her to be the standard bearer of white bulbocodium cultivars, rounder, smoother and a little less petunia-flowered than cantabricus. If you want to wake up on a fine spring morning to a sea of happy white hoop faces in your garden this is the one to make it so. Said to be fragrant, but when petticoat blooms for us it is cold and the ground is so very far away from our olfactory nerves. Many bulbocodium enthusiasts grow this division in pots in the greenhouse, that's an easier sniff laboratory.
