i have about 10 acres of pollinator plantings and its pretty easy to collect a good amount of seed once its ripe, you need to beat the birds to the forb seeds though, they are after them right when they are ready. I started looking for little pockets of cool season grass in late summer, then spraying it with gly so i can then frost seed either NWSG or wildflowers into it late winter, it works good and over time you can really improve little pockets of cover all over the property. Im also game for a seed excchange next year!
