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.

Every seed variety we sell is non-GMO.

  • 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.
