Since my first year of hybridizing daylilies, I've never germinated them any other way than in the fridge. The first year, I stored them in the fridge, and then planted them in small pots to germinate, under lights. Had okay success, but not close to 100%. Since then, I've kept all of them in the fridge until they have sprouted, and I've have perfect success. Don't want to mess with perfect!
