peas love cold! at least to germinate. they like a cold period and if they make it through the wet without rotting, they do pretty well. I haven't tried fake stratification of peas, like putting them in the fridge for a week or two, then planting outside.

I had to bring inside all my plants that had been hardened off. grr. At least the 80 deg weather didn't fool me enough into actually planting anything.
