Start seeds inside 3/21, 1/16" deep. Keep seeds (but not soggy wet) moist until germination. Transplant outside May-June 12-18" apart. Full sun or part shade. Or, direct sow outside 3/1-7/15. Prepare area by loosening soil surface with a rake (remove weeds if possible). Hand broadcast (sow) seeds evenly over area. From seed, these plants can take 1-3 years to become established and large enough to flower. We recommend sowing several species of native plants together such as “Save the Bees” or “Good Bug Blend.” We also recommend sowing annual plant seeds to fill in the area until the native plants get established. Try Blanket Flower, Hopi Red Dye Amaranth, Dyer's Coreopsis or Kale.
Clip individual leaves or flowers, but don’t remove more than 1/3 of the leaves at one time unless you are taking the whole plant.
Harvest seeds by shaking mature and dry flower heads into a bucket or bag, or clip seed heads and thresh. Separate chaff by screening and winnowing.
