Thin-leaved Coneflower is a biennial plant that flowers in its second year. It is considered a short-lived perennial, but reseeds easily and will come back year after year once established. It blooms flowers with a dark brown center disc and bright yellow radial petals that provide a cheery pop of color. It grows best in full sun, but can tolerate part sun with some support, as it tends to droop in shadier conditions.
