Low germination rate for strawflowers, how long do they last?
This spring I planted two whole packets of strawflower seeds that I purchased just a few weeks before. I got less than 20 seedlings from over 200 seeds. A few years before I must have planted over 400 strawflower seeds that were a few years old from the Dollar Tree and NONE of them germinated.
Does anyone know how long these seeds can be stored?
