Yellow coneflower has large daisy-like flowers with drooping petals surrounding brownish prominent cones. Echinacea paradoxa starts blooming in mid-June and keeps producing lots of flowers on long green stems through July, especially if deadheaded. Yellow Coneflowers prefer good drainage, and can self-seed if the seedheads are left to ripen. They provide a valuable seed source for finches in fall, but the plants will over-winter better if most of the flowers are removed when spent. The long leaves are smooth and lance shaped.
