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.

Eureka County, Nevada is in USDA Zone 5b. The average last spring frost is May 30 and the first fall frost is September 20, giving you a growing season of approximately 113 days.

At an elevation of 8,408 feet, Eureka County receives approximately 14.7 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 92°F, providing good warmth for Gaillardia (Blanket Flower) during the growing season. 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. With low rainfall, drip irrigation is essential for growing Gaillardia (Blanket Flower) successfully. Mulch heavily to conserve soil moisture.

Gaillardia (Blanket Flower) Heat Requirements (GDD)

What are Growing Degree Days (GDD)?

Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" — every day above 50°F deposits warmth that helps your plants grow.

Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.

Gaillardia (Blanket Flower) needs ~1,615 GDD — county provides 2,147 GDD Excellent fit

Growing Tips for Gaillardia (Blanket Flower) in Eureka County

Direct sow Gaillardia (Blanket Flower) outdoors after May 30 in Eureka County when soil has warmed and frost danger has passed.

Sandy soil in Eureka County dries quickly — mulch Gaillardia (Blanket Flower) with 2-3 inches of straw and water deeply 2-3 times per week rather than lightly every day.

Your 113.0-day growing season in Eureka County is tight for Gaillardia (Blanket Flower) (70.0-100.0 days to maturity). Start indoors and choose early-maturing varieties.

Common pests for Gaillardia (Blanket Flower) in this region include aphids and slugs. Use row covers early in the season and inspect plants weekly.

Eureka County receives only 15" of rain annually. Gaillardia (Blanket Flower) needs consistent moisture — install drip irrigation or water deeply 2-3 times per week.

General growing tips

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.
