When to Plant Gaillardia (Blanket Flower) in Cottle County, TX

Gaillardia (Gaillardia aristata), the native blanket flower of the American West, is one of the most floriferous and longest-blooming perennials available — producing cheerful, daisy-like flowers in fiery red, orange, and yellow combinations from early summer through hard frost in most climates. Named for the way its spreading colonies mimic the patterned blankets of Indigenous American weavers, gaillardia thrives in the exact conditions that challenge other perennials: poor, dry, gravelly soil in full sun. An outstanding pollinator plant, attracting bees, butterflies, and finches that feed on its seed heads. Somewhat short-lived (3–5 years) but self-seeds freely to sustain garden colonies.

Cottle County, Texas is in USDA Zone 7b. The average last spring frost is March 30 and the first fall frost is November 9, giving you a growing season of approximately 224 days.

At an elevation of 3,553 feet, Cottle County receives approximately 59.3 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 97°F, so Gaillardia (Blanket Flower) may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring — great for early planting — but Gaillardia (Blanket Flower) will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Gaillardia (Blanket Flower) root diseases.

Growing Tips for Cottle County

Start seeds indoors 6–8 weeks before last frost or direct-sow after last frost. Seeds need light to germinate — press onto soil surface without covering, or cover very lightly (1/8 inch). Transplant after last frost when soil has warmed. Lean, well-drained soil is essential — rich or wet soil causes sprawl and root rot. Deadhead spent blooms to prolong the season, but leave some heads for self-seeding to renew the planting. Divide every 2–3 years in spring to maintain vigor. Drought-tolerant once established; overwatering is more damaging than underwatering. Year 2+ plants deliver the fullest multi-season bloom.
