Open Pollinated, and Organic Seed

Coreopsis, Tall Plains (Organic)

Coreopsis tinctoria.

Tall Plains coreopsis is the true original of the coreopsis clan. The plants are loaded with bright yellow flowers that have dark maroon centers. Blooms reach 2” across, petals have nice jagged edges. Plants grow to 3′ with ferny foliage. A great low maintenance addition to the flower garden, with a sea of blooms. Flowers make excellent filler in bouquets, create superb pollinator habitat over a long season, and songbirds love them for cover and forage, too. Blooms right up until frost. Thrives in disturbed areas and wet soils but is also drought tolerant, naturalizes easily and is deer resistant. What more could you want? Native to the plains of the US and has naturalized throughout most of the country. Self-seeding annual. Aka, Calliopsis, Tickseed.

Direct sow 1/4” deep after danger of frost, or sow indoors for transplant 6 weeks before last frost. Thin/ transplant to 12”. Plants prefer full sun. Deadhead to prolong bloom and limit self-seeding.

Seed Saving

Collect seeds from seed heads that are fully dry. Shell by hand or by dancing, winnow or screen to clean. Some cross-pollination may occur, isolate from varieties of the same species by 1/4 mile.

      We direct sow after average last frost or sow for transplant in April. 12-18 in. between plants is optimal but they will tolerate much closer. Annual coreopsis is a very forgiving and easy to grow plant. USDA NRCS says “Broadcast or shallowly drill 1-2 grams per 100 square feet (1-2 lb/acre).”
