I have some seed from a couple eastern US native wildflowers, Wood Poppy, Stylophorum diphyllum, and common Columbine, Aquilegia canadensis. Never having grown either from seed intentionally I can't say what they would require in terms of stratification, if any. They both self seed vigorously under good conditions. Being native to the eastern US, a cold damp stratification isn't going to hurt! Shipping will be on me, only qualifications are that you be a participating member of the community, and live in the US. Winning number selected Sunday, 6/28 by my grandson.
