Celebrated for its thick stems that support 3- to 4-inch flowers, 'Flame Thrower' coneflower ignites the garden with its two-toned blooms. Petals fade from red-orange at the center to gold edges. Cones contrast in copper shades. For garden artistry, partner it with peach-toned coralbells or 'Autumn Joy' sedum. Plants reach 40 inches high in bloom and are hardy in zones 4 to 9.
