Plains Coreopsis is native to the central plains of North America and has become naturalized in much of eastern North America. A bushy, multi branched plant produces large numbers of bright yellow flowers with maroon highlights. A great plant for wildflower mixtures and for quick first year colour. It is generally considered an annual or short lived perennial. While this plant will tolerate drier conditions, it grows best in years with average to above average rainfall. Plains Coreopsis tolerates partial shade but does best in full sun. Plants grow from 45 to 60 cm (18-24″) in height. Another good plant to attract pollinators and the seed is browsed by small birds.

How to Grow
3,640 seeds/gram. Start seed indoors in a soil-less mix in early spring for mid summer blooms. Germinate at 24 C (75 F) for 5 to 10 days then grow on under lights at a slightly cooler temperature before hardening off and planting outside in a sunny spot. Outdoors, direct sow seed in mid May to early June and keep the soil moist during the germination period. Thin the seedlings to stand 30 cm (12″) apart in the garden. Plant will often self-seed in the garden.
