Indian blanket flowers (Gaillardia pulchella) are brightly colored annuals that grow from 12 to 18 inches in height. The flowers bloom repeatedly from midsummer to mid-fall when planted in full sun within their USDA hardiness zones (3 to 10). The Indian blanket flower needs very little water once it becomes established in the landscape, making it a plant to consider for the xeriscape garden. Plant the Indian blanket seeds in the spring when the soil has warmed to at least 70 degrees F.
Choose a location in the garden that receives at least six hours of sun per day.
Amend the soil in the flower bed by adding a 3-inch layer of sand and mixing it, with the garden fork, to a depth of 8 inches. Level the bed with a rake.
Push the Indian blanket seeds one-eighth inch into the soil, 12 to 18 inches apart, depending upon the effect you hope to achieve.
Water the planting bed with the fine mist setting on the hose so you don't wash the seeds away, and keep the soil moist until the Indian blanket seeds germinate. This should occur within three weeks.
