We guarantee that you will receive high quality, source-identified prairie seed every time you order from Heritage Seedlings. Our seed is tested by an independent lab for purity and germination using standard procedures of the Association of Official Seed Analysts.
All of our seed is sold "PLS" (Pure Live Seed) unless otherwise indicated. A pound of "PLS" is the actual weight of seed required to equal one pound of 100% pure, viable seed. This is calculated based upon current purity and germination tests. So although seed you order and prices are per PLS pound, the actual weight you receive will be more.
For example: Lomatium dissectum 2016 lot - Purity% (0.98) x Germ % (0.69) = 0.676 (this is the PLS correction factor). To determine how much bulk seed is needed to equal 1 PLS lb, one is divided by 0.676 = 1.47. Therefore, 1.47 bulk pounds of Lomatium dissectum seed is equivalent to one PLS pound.

To order, please E-mail Us with your specific requests or questions. If you know what you would like, please use the Order Form above.
Please browse through our list of native plants. All are native to the Willamette Valley, and many occur in other western states (consult your local flora). Habitat abbreviations are explained in detail under Native Habitats for Our Seed.
Heritage endeavors to collect seed on a regular basis from numerous wild populations to ensure the generation in production does not extend past the second generation for perennials and the third for annuals; and there is a broad genetic representation for each species. We pride ourselves in offering a diversity of forbs, many not readily available. Many species are only available in small quantities due to the challenges of growing them for seed production on a large-scale. These species can still be part of your landscape or restoration project by selectively sowing them in small plots using a garden seeder or hand sowing.
If you would like to know if a particular species is native to your area of Oregon, please consult The Oregon Plant Atlas at http://www.oregonflora.org/atlas.php
