I just read somewhere that someone put some Echinacea purpurea seeds into a bag with compost into the fridge (to germinate) and forgot about them, then took them out over 6 months later and they had sprouted and were still doing well. Planted them out and they are thriving. I guess you can but try, like most things, sometimes it works, sometimes it doesnt.
Planting time is usually Feb-June anyway, I also read that they germinate better if you pop the seeds in a bag with sand for 2 weeks in the freezer, they germinate well, so you might be as well to get started now.
By the way, If you do have a go at it now, would you let me know how they do.. The weather is very mild here and most of my spring grows is already in full swing..
