How to store, and where to buy?
We are big into seed saving, so no need to buy each year. Store seeds in airtight containers in a dry, cool dark place. Most will last for many years. We buy most from Johnny’s, High Mowing, and Territorial Seed. Also Baker Creek for more heirloom (open pollinated) varieties which are what you want if you’re looking to save seed as they will breed true to type.
