Double the Sun
Coreopsis Seeds
Coreopsis grandiflora
Big clear golden yellow, semi double, 2½ in. flowers appear 2-3 weeks earlier than comparable coreopsis, such as Early Sunrise. The 12-15 in. tall, nicely shaped, easy to grow plants begin to bloom during cool spring weather and continue to flower heavily through the heat of summer. Double the Sun coreopsis brings a long season of low maintenance color to the front of your borders, flower beds and planters, and along garden paths.
Growing Double the Sun Coreopsis Seeds
Plant Coreopsis Seeds: Sow coreopsis seeds in cell packs or flats, press into soil but do not cover. Needs light to germinate. Kept at 65° F., germination is in 21-30 days. Transplant into the garden 1-1.5 ft. apart.
Grow Coreopsis: Full Sun. Rising Sun, Sterntaler, Sunburst, and Sun Up coreopsis are heat and humidity tolerant, and will thrive with moderate to little water. American Dream coreopsis likes mild summer temperatures, afternoon shade in warm climates and moist, even wet soil. Coreopsis require little maintenance, and are rabbit and deer resistant. Shear plants back occasionally to promote continuous flowering. Coreopsis flowers attract bees, birds, and butterflies.
