This native meadow derivative is a compact version of the species. It blooms from midsummer into early autumn, with prominent, copper-orange central cones surrounded by drooping, rose- or purple-pink ray petals. It will reach 24 inches if not cut back.
 Noteworthy characteristics: Medicinal. Attracts butterflies, bees, and birds in winter if cones are left on plant. 
 Care: Grow in deep, well-drained soil in full sun. It is tolerant of drought, heat, humidity, and poor soils. Cut back stems to promote more flowering and reduce excessive self-seeding. Deadheading prolongs flowering.
 Propagation: Sow seed at 55°F in spring. Divide clumps in spring every 3 to 4 years. Take root cuttings from autumn to early winter.
 Problems: Leaf miners, powdery mildew, bacterial spots, and gray mold. Vine weevils may feed on roots.
