Plant Sale Text: This yellow-flowered coreopsis is one of the roadside wildflowers that make summer driving a little brighter. It can be found in lean soils at woods’ edge blooming its little yellow heart out. Greater tickseed is tolerant of drought and humidity, but prefers well drained soils. This is a good wildlife plant, its nectar will attract pollinators and its seed will attract birds. One feature that distinguishes this plant from many other garden-worthy coreopsis is that its opposite compound leaves give a graceful whorled impression.

COMMENTS: Woodlands; common (rare in GA, NC, SC, VA). May-Jul. W. VA, s. OH, and KY south to SC, GA, w. FL, s. AL, and s. MS. How to treat the Coreopsis major complex (here including C. major var. major, C. major var. rigida, C. delphiniifolia, and C. verticillata) is not clear. The group apparently includes diploids and a variety of allopolyploids and autopolyploids (at various ploidies) variously derived from C. major var. major and C. verticillata.
