Open-pollinated
Last reviewed 2026-10-04
Open-pollinated describes a plant variety whose flowers are pollinated by natural mechanisms such as insects, wind, or self-pollination rather than a controlled cross between selected parent lines. Seed from an open-pollinated variety can reproduce the variety's general traits when the crop is isolated from related varieties and selected carefully.
What it means
Open pollination does not mean that every seed is genetically identical. Pollen can move between compatible plants, and some crops cross readily while others mostly self-pollinate. Seed saving therefore requires knowledge of the crop's flower structure, isolation distance, and selection goals.
How it affects the garden
Open-pollinated varieties are useful for gardeners who want to save seed or maintain a variety over time. Label saved seed with the variety, year, and growing conditions. Do not assume saved seed will be true to type if another compatible variety was flowering nearby.
Pollination also affects fruit set in the current season. The plant spacing calculator helps leave room for healthy plants, but spacing alone does not prevent every cross. For uncertain seed, a germination test checks viability, not genetic identity.
Example
A gardener grows one open-pollinated bean variety and saves mature, dry seed from healthy plants. If no compatible variety was nearby, the next generation is more likely to resemble the parent planting.
Common confusion
Open-pollinated is not a guarantee that seed is heirloom. It is also not a synonym for organic. Hybrid seed can be excellent, but saved seed may not reproduce the same combination of traits.
