Gaillardia aristata

Gaillardia aristata is a North American species of flowering plants in the sunflower family known by the common names common blanketflower and common gaillardia. This perennial wildflower is widespread across much of North America, from Yukon east to Québec and south as far as California, Arizona, Illinois, and Connecticut, although it may be naturalized rather than native in parts of that range. It is also naturalized in scattered locations in Europe, Australia, and South America.

Gaillardia aristata grows in many habitats. It is a perennial herb reaching maximum heights of anywhere between 20–70 centimetres (7.9–27.6 in). It has lance-shaped leaves near the base and several erect, naked stems holding the flowers.

Easily grown in average, dry to medium, well-drained soils in full sun. Prefers moist, organically rich soils that drain well but tolerates dry soils and drought. Performs poorly in unamended, heavy clay soils typically found in the St. Louis area. 

Deadheading spent flowers is not necessary, but will tidy the planting and may encourage additional bloom. If flowering declines or stops in summer, consider cutting back plants to encourage a fall bloom. ‘Bijou’ is a seed strain that will self-seed in optimum growing conditions if flowers are not deadheaded.

Each flower head has a center of brownish or reddish purple disc florets and a fringe of ray florets which are about one to three centimeters (0.4-1.2 inches) long and yellow to reddish with dark bases.


The fruit is a stout, hairy achene which may be over a centimeter (>0.4 inches) long including the long, spiky pappus.

Gaillardia aristata is a species of blanket flower that is native from North Dakota to Colorado west to California and British Columbia. It typically grows in clumps to 30” tall and is found primarily in dry sites on meadows, prairies, grasslands, mountain foothills and at lower mountain elevations to 9000’. ‘Bijou’ is a dwarf seed strain that typically grows to only 10-12” tall. It features orange-red daisy-like flowers (to 3” diameter) with yellow tipped rays. 

Blooms late spring to fall. Lance-shaped gray-green leaves may be pinnately lobed near the base of the plant. Flowers are attractive to butterflies. In areas where goldfinches are present, gardeners should consider leaving some spent flowerheads for the birds. 

Gaillardia is sometimes commonly called blanket flower in probable reference to the resemblance of its rich and warm flower colors and patterns to blankets woven by Native Americans. 

However, some authorities suggest that the name blanket flower was originally derived from the habit of wild species plants to form colonies that blanket the ground. Specific epithet means bristly in reference to the hairs that cover the flowerhead receptacles, stems and leaves. The popular but short lived gaillardia hybrid sold in commerce as G. x grandiflora are crosses between perennial G. aristata and annual G. pulchella.
