Coreopsis lanceolata. Native to eastern North America, Lanceleaf Coreopsis has naturalized across much of the Prairies and even into the Rocky Mountains. It is a hardy perennial plant (Zones 3-10) that is both drought tolerant and able to endure high temperature and humidity. It will work in well drained containers and just about any garden soil, but it prefers well drained, nutrient-poor, sandy loam. This variety can reach 90cm (36″) tall, but may grow shorter depending on exposure in the garden. It’s stems are stiff and upright, so it makes a nice cut flower. It is attractive to a wide range of pollinators and beneficial insects. Avoid over-watering, and keep the spent flowers picked — otherwise it requires little care.

Season & Zone
Exposure: Full sun
Start indoors mid-February to late March for transplanting out after last frost – April is safe on the coast. Or direct sow mid-March (ideal) to mid-May. In areas where winter is mild, you can direct sow in the fall, as well. Seeds germinate in 5-25 days. If starting indoors, maintain soil temperature at 12-21°C (55-70°F) and provide bright light.
Sow seeds on the surface of the soil. Transplant or thin to 15cm (6″).
Deadhead often and do not feed, as fertilizers can reduce flowering. Coreopsis will adapt to many different soils, but prefers well drained, rich soil. This annual species may self sow.
