GMO: (Genetically Modified Organism) SeedGeeks does not carry genetically modified varieties. Genetically modified varieties have had their DNA scientifically altered to make them more pest, disease, or chemical resistant. GMO seeds are controversial because no one is sure of their long term effects on the environment and humans.

Heirloom Seed: An open-pollinated seed variety that has been passed down through the generations for at least 50 years.

Hybrid: A variety created by crossing two separate varieties to achieve desirable characteristics. A hybrid tomato, for example, may have been created to have disease resistance, produce uniform, prolific fruit, or have superior flavor. If you save the seeds from a hybrid, though, the resulting fruit next year may revert back to the characteristics of one of its parents. SeedGeeks does not carry hybrid varieties.

Open-pollinated: Varieties that are pollinated naturally by wind or insects without human intervention. Because there are no restrictions on the flow of pollen between individuals, open-pollinated plants are more genetically diverse. Saved seed will be true to the original variety, as long as pollen is not shared between different varieties within the same species. All SeedGeeks seeds are open-pollinated.

Organic Seed: Organic refers to the way agricultural products are grown and processed. Organic seed, much like organic food production, is based on a system of farming that maintains and replenishes soil fertility without the use of toxic pesticides and inorganic fertilizers. This ecological management system promotes and enhances biodiversity, biological cycles, and soil biological activity.

Untreated Seed: Seed that does not have any coating, chemical or treatment applied to the seed. All SeedGeeks seeds are untreated.
