Suggestions for Plant Sale

I found out that I am going to be raising seedlings for two different fund-raiser plant sales in May. I need to start more plants than I originally intended. Does any one have suggestions for plants that are cold-hardy or need cold stratification that can be started outdoors about now? I could double my seedlings if they didn't all need to be indoors under lights.

Pollen, there is a newsgroup here on Daves Garden about winter sowing. Has alot of useful tips. Somehow the link wont post ah here it is http://davesgarden.com/community/forums/f/coldsow/all/
