I use the "sow mass quantities method" myself. I feed the birds near the house and have the annuals garden a good 100 feet away. I love poppies and there are a few other flowers that are best sown in fall/winter that I also like, Clarkia is one that comes to mind.
Mixing them with coffee grounds is an interesting idea, but that will sure be nasty looking on the snow, LOL. Anyone wanting "persian blue" poppy seeds, I have a million of them.
