Organic, Non-GMO and Heirloom Seeds in Packs & Bulk Selection Guide

Explore vegetable, herb, and flower seed in packet and bulk sizes. This collection includes products with different attributes: certified organic, conventional, non-GMO, heirloom, hybrid, and open-pollinated. These terms are not interchangeable and do not apply to every product shown.

  • Certified organic: Confirm the certification statement on the individual product page and package.
  • Non-GMO: Describes genetic-engineering status; it is not an organic certification.
  • Heirloom and open-pollinated: Describe breeding and seed-saving characteristics; they do not by themselves mean certified organic.
  • Hybrid: Hybrid seed can be conventional or certified organic, depending on the product.

Use the category links and individual product listings to select the attributes, crop type, package size, and planting guidance you need.
