Coneflower - Grey Head Pinnate Prairie Coneflowers ( Ratibida pinnata) Yellow Cone Flower
Height 3 to 5 ft
Pinnate Prairie Coneflower, also known as Gray Headed Coneflower, Gray Head Mexican Hat, Yellow Coneflower, and Prairie Coneflower, is a native perennial species in the Asteraceae family that makes a real statement when planted en masse, or in a wildflower meadow.
Plants have branched, slender, and hairy stems that bear single stunning flower heads with drooping bright yellow rays arranged around a roundish to ellipsoid shaped - upward facing - tall grey central disks that turns dark brown as the rays drop off. Lower leaves are long and divided into leaflets, while the upper leaves are smaller. Each plant produces over a dozen stalks; one or several flowers, each on its own long stalk, may top a single stem. Plant is native to the central and eastern United States and (Ontario) Canada.
NOTE: A similar species, Upright Prairie Coneflower (Ratibida columnifera), is a shorter plant; its central disc is columnar, 2-4 1/2 times as long as thick. When bruised, the central disc exudes an anise scent
