How to Grow a Green-Headed Coneflower

Related to the familiar black-eyed Susan, the green-headed coneflower has yellow, recurved petals surrounding a green "eye" as opposed to black. Also known as cutleaf coneflowers, they have light green, oval leaves with three deep, pointed lobes. They are native to most of the U.S., perennial and hardy. These tall flowers grow 3 to 4 feet in cultivation and bloom from July through September.

Instructions

    • 1

      Select a planting site in full sun or part shade with well-drained, slightly acidic soil.

    • 2

      Sow seeds in the fall before the first frost while the ground is still workable. The seeds require a period of cold, moist conditions to germinate. Plant at a depth of one-half inch and space seeds about 12 inches apart. Irrigate after planting.

    • 3

      Keep emerging seedlings moist and provide 1 inch of water weekly during the following summers. Green-headed coneflowers don't tolerate drought well.

      Divide every three to four years for optimal growth.
