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.

Companion planting is planting seed varieties near each other to benefit one or more of the plants. Some plants benefit each other by attracting beneficial insects, keeping away unwanted bugs. Others aid in pollination. Some plants have working relationships with each other and others have antagonistic (hostile) relationships.

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