How many years to keep flower seeds?
I seem to make a habit of buying commercial flower seeds and than not get around to planting them. I was sorting some old seed packages and realized some were dated 2002. These include nasturtium, Calif. poppy, nemesia, asclepias, linum lewesii, etc. Should I consider these seeds to be too old to germinate properly and just throw them out? What is your experience with old(er) seeds?
