This is an heirloom seed, meaning it has been passed down from generation to generation for at least 75 years. As a rule, heirloom seeds taste better and will grow the same year after year.

These are also open pollinated meaning they will reproduce themselves. While all heirlooms are open pollinated not all open pollinated seeds are heirlooms.

These are open pollinated seeds. Pollination occurs by insect, bird, wind, humans, or other natural mechanisms. Because there are no restrictions on the flow of pollen between individuals, open-pollinated plants are more genetically diverse. However, as long as pollen is not shared between different varieties within the same species, then the seed produced will remain true-to-type year after year.

Freshly Packed: These seeds are packed for the current growing season and will provide high germination rates next year as well.
