Age old Columbine seed
I am posting to see if anyone is familiar with Columbine seed viability past one year- 2 years since collection. I collected Columbine seeds and saved them in an envelope, they were forgotten along with moving from apartment living to our permanent home. My husband and I found them in a special keepsake box from a few years ago. I am pretty sure they are over 2 years old.
My thought was giving them a chance and broadcasting them onto bare sandy soil in early May and seeing what happens. I believe it's still better to give them a chance now than never.
Also if this fails, would a fall sowing of fresh seed directly into the sandy soil bed, or pampering them inside over winter work better for a winter that is known to hit -15?
