www.wintersown.org has some great lists of flowers etc., and here is their list for hardy annuals that can be wintersown. As it happens many of these flowers can still be sown with freezing temps in the spring, as well as sown with warmer temps later on. It amazes me that however particular requirements for germination of any given plant may be, that still there often are many other alternative ways to germinate those seeds.
