Slender Gaillardia or Hopi Blanketflower or Red Dome Blanketflower Asteraceae:
Perennials with bright yellow flowers around flat, brown-red center cones. The foliage is narrow and deeply cut. Does well in dry soils under hot conditions, not as a prolific bloomer as the others listed but does bloom in late spring and often into fall. Showy displays of flowers end 1 to 1.5 foot tall stems. Self seeds readily on open, sandy soils. Makes a nice addition along a gravely roadside. Where not winter hardy plants can be grown as annuals.
