I have bought many store bought seed packages over the last 3 years when I got my greenhouse built and planted up a storm. now I have made more plants than I need and still have seeds left over.
Does anyone know the shelf life of store bought seeds, they have been kept in a cool area and not exposed to dampness.
If anyone is interested in them I will make a list and post. all are for zone 8

This is a pic of the poppys I started from seed, very hardy even blooms in the snow never dies down.
