Triple-tested seed qualityRegular quality and germination checks support every packet.

We regularly test seed quality and germination as lots move through storage and packing. We stand behind the seed we send and want customers to contact us when a packet does not perform as reasonably expected.

1-year seed warrantyCoverage begins on the date of purchase.

When properly stored, planted, and cared for, we guarantee reasonable germination and true-to-type growth for one year from the date of purchase. Conditions outside our control—including extreme weather, pests, unsuitable storage, and gardener error—are excluded. Contact us when something is not right so we can review the situation and work toward a replacement, refund, or another fair resolution.

Non-GMO / BE seed policyWe do not buy or sell genetically engineered or bioengineered seed.

Every seed variety we sell is non-GMO.

USDA’s National Bioengineered Food Disclosure Standard defines bioengineered foods as containing detectable genetic material modified through in vitro recombinant DNA methods in ways not achievable through conventional breeding or found in nature.

  • Hybrid means parent lines were conventionally crossed; hybrid does not mean GMO.
  • Heirloom and open-pollinated describe how a variety is maintained and reproduced.
  • Organic certification is separate and is shown only when verified for the individual product.
