These North American native milkweeds are hardy perennials that will tolerate full sun to partial shade and thrive in a wide variety of soils.
For best results, expose seeds to moist, cold conditions (stratification) prior to sowing. For cold stratification, place seeds in moist potting soil or sand and store in a refrigerator for 4-6 weeks. After stratification, sow seeds in containers or direct seed outdoors after the danger of frost has passed. Sow seeds 1/8-1/4″ deep and 6-8″ apart. Optimal soil temperature for germination is 65-80˚F. Seeds will sprout in 10-28 days. Thin seedlings so that mature plants are 24-36″ apart.
Seeds can also be direct sown outdoors in the fall where they will stratify naturally and germinate the following spring.
Based in Asheville, NC, Sow True Seed has a small, dedicated staff of dirt worshippers committed to providing high quality, open-pollinated seeds in support of sustainable food production and regenerative agriculture. Founded in 2008 by lifelong gardener and food activist Carol Koury, Sow True Seed was created to preserve our shared botanical heritage and grow a new era of ecological wisdom.
Sow True Seed supports independent, regional agricultural initiatives that foster a vibrant, sustainable economy, and true food sovereignty. They are committed to growing our awareness and actions to honor the heritage of their seeds, the diverse people and places that have contributed to our collective abundance.
Based in the glorious mountains of Western North Carolina – home to a temperate rainforest and one of the most biologically diverse areas of North America – Sow True prides themselves on working with farmers in the region who ensure the survival of heirloom varieties that would otherwise become extinct.
The United States Department of Agriculture (USDA) requires that seed germination rates be tested at least once a year. A “sell by date” is also required on seed packets and cannot date more than a year from the last passing germination test. Sow True Seed tests the germination rates of all seed varieties twice a year via the North Carolina Department of Agriculture to ensure passing germination rates. The sell by date is not a “use by” date; most seed varieties, stored properly, can last up to three years. Sow True Seed stores all seed varieties in a climate controlled facility that averages 50° F and 50% humidity, which are ideal seed storing conditions. For the home gardener the best way to store seeds is in the refrigerator, in a zip top bag or Mason jar, with silica packets to absorb any moisture. We do not recommend storing seeds in the freezer.
