Does anyone have a recommendation for a place on the web that sells
wildflower seeds? I've been to a few places and there does seem to be
some variations. One site lists all their plants and percentages of each
in the seed mix and I kind of like that. I'm going to totally avoid
hummingbird mixes because although they look nice when they start to
bloom, by August they really peter out.

I'm looking to buy about 1 lb wildflower and 1 lb poppy and this year I
want to plant them in the fall instead of spring to see how that turns
out. I'm in zone 5 (Chicago) BTW and sometimes, like this year, the
spring was so cold that the seedlings didn't start until June when
planted at the beginning of May. I'm hoping a fall planting will cause
some of the hardier plants to start before the leaves start growing on
the trees.
