    I not only see this lovely perennial in some prairie or meadow restorations or naturalistic landscapes, but also in some conventional gardens, as it is sold by a good number of both native plant and conventional nurseries. This species has 5 to 10 yellow ray flowers around the disc flowers in the composite inflorescence that droop down. In nature it grows in dry or mesic soils from southern Ontario down to Georgia, Arkansas to Oklahoma. It should have an anise-scented odor when the foliage is bruised. Easy to grow, low maintenance.

    This was one of my surprises this summer, blooming outside of the border of our prairie to be. I am not a fan of yellow composite flowers, but the overall shape of the flower with its droopy petals does make this flower stand out among the rest. Besides Gray-headed Coneflower and Yellow Coneflower as common names, the lesser-known Weary Susan more aptly describes this plant and does not confuse any into thinking this to be an Echinacea species.

    This plant is native to the United States, but I like this plant moreso because it's a food source for the birds. It was the birds that helped me find the seeds when I did not think they would be easy to harvest.

    The Gray Headed Coneflower is a plant of dry, thin woods, roadsides, and prairies of the south central states. These perennials grow two to four feet tall and have clumps of deeply cleft leaves. Flowering occurs in early to mid summer. The daisy-like flowers have five to ten bright yellow drooping ray flowers (petals) about one to two inches long. The cone or center of the flower is grayish-green and becomes darker and taller with age eventually looking like an inch tall thimble. This plant is easy to grow in dry or wet soils in full sun. Good for a meadow.

    "Ratibida pinnata is a species of flowering plant in the aster family known by the common names pinnate prairie coneflower, gray-head coneflower, yellow coneflower, and prairie coneflower. It is native to the central and eastern United States and Ontario in Canada.

    This species is a perennial herb which can well exceed one meter in height. It has fibrous roots and rhizomes or woody caudices. The rough-haired, glandular leaves are up to 40 centimeters long and are divided into several large lance-shaped or oval lobes. The inflorescences are tall, generally far above the highest leaves. Each flower head contains up to 15 yellow ray florets up to 6 centimeters long. The center of the flower is globular or oval in shape and measures up to 2.5 centimeters long. It is covered in up to 200 or more disc florets which are yellow-green to purplish in color. The disc heads have a scent reminiscent of anise when crushed.

    This plant grows in prairies, on the margins of woods, and on roadsides. It can grow in moist or dry habitat. It is hardy and not easily outcompeted by other plants.

    This plant is grown as an ornamental garden plant. It is attractive to butterflies and birds"
