Description

Coreopsis is a hardy, North American native perennial with attractive flowers that are attractive to butterflies and other pollinators. Most types are hardy in zones 5 to 9, but some are hardier. New breeding has resulted in a much wider range of flower colors. Coreopsis is good in garden beds as well as pots and mixed containers.

How To Plant

Set plants so that roots are slightly deeper than when in the pots.

Seed varieties can be planted outdoors after the last frost in spring, or indoors 8 to 10 weeks earlier. Surface sow or cover seed just slightly. Maintain at 65 to 78 degrees and expect germination in 7 to 14 days.

Maintenance

Fertilizer Recommendations

Common Problems

Usually not seriously troubled by pests or diseases. Powdery mildew can sometimes affect plants.

Alternative Products

Product Recommendations

Control powdery mildew outbreaks with 70% neem oil. or use Serenade as a preventative, before symptoms occur.
