Anyone want to share/trade seeds

I bought my first home two years ago and am trying to establish a diversity of native plants, and a few non-invasive ornamentals that provide nectar when few natives are in bloom, as well as edible and useful plants.  

The Butterfly weed I planted last year is blooming now, and hopefully there will be some other flowers soon.  Mostly common stuff like Echinacea and Rudbeckia, common milkweed...

If anyone has seed to share or trade please let me know.  I feel like seeds should be free, and I plan to do more guerilla gardening and might even start a native plant club in my town.  I want to get more proactive about slowing down this insect apocalypse.
