Gaillardia, also known as blanket flower, is an easy-to-grow, short-lived perennial with richly colored, daisy-like flowers. The plant forms a slowly spreading mound, and the common name may be a reference to how they can slowly spread and “cover” an area.
compost.
The plants grow to about 24 inches in height with about a 20 inch spread. Felt flowers are fast growing. If grown from seed, they will flower in their second year, but plants purchased from nurseries are usually ready to bloom in your garden. This garden favorite puts out large showy flowers in shades of red and yellow during the warm seasons.
These short-lived perennials are usually planted from nursery starts, but they also grow easily from seeds planted directly in the garden after the last frost date (or started indoors about 4 to 6 weeks early). Note that felt flower is slightly poisonous to humans. 1
Gaillardia X Grandiflora is fully hardy in USDA zones 3 through 10. Due to extensive hybridization, you will likely be able to find a variety that suits your zone and climate conditions. The flower can be reseeded and spreads easily through your garden. Since the original plants are hybrids, expect some variation from self-seeding.
Gaillardia are such tall flowers that they work equally well in borders and containers. Blanket flowers do well with other heat-loving plants that thrive in full sun. The bold, daisy-like flowers blend especially well with soft textures, such as wire-leaved Coreopsis and cosmos, as well as airy ornamental grasses. For more contrast, plant them with spiky plants such as Kniphofia, Crocosmia or daylilies. ‘Burgundy’ contrasts well with blue flowers, such as Salvia and Veronica. All Gaillardia varieties make excellent cut flowers.
Light
These plants thrive best in full sun. The blanket flower can handle some partial shade, especially in warm climates, but they get a little floppy and don’t bloom as much.
Soil
Gaillardia prefers poor soil. Do not amend with rich matter or over-fertilize. It is not particular about soil pH, but it needs well-draining soil. It will grow in slightly moist conditions, but heavy clay soil will probably kill it.
Water
Immediately after planting, water deeply to encourage good root development. Check the soil frequently (every other day or so) to make sure the soil is moist but not soggy an inch below the soil line. Once established, Gaillardia is extremely drought tolerant. It can go without watering unless there are extremely hot and dry conditions, then it is best to water the bed once or twice a week. Avoid overwatering.
Temperature and humidity
Felt flowers thrive in full sun and can withstand hot summer temperatures. They do not require a humid environment and do better in warm, dry climates than cool, humid ones. In cooler climates, protect your overwintered blanket flowers with a thick layer of compost.
