- First harvests: gaillardia (blanket flower)
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.
Champaign County, Ohio is in USDA Zone 6a. The average last spring frost is April 25 and the first fall frost is October 17, giving you a growing season of approximately 175 days.

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.

Growing Tips for Gaillardia (Blanket Flower) in Champaign County
Direct sow Gaillardia (Blanket Flower) outdoors after April 25 in Champaign County when soil has warmed and frost danger has passed.
Common pests for Gaillardia (Blanket Flower) in this region include aphids and slugs. Use row covers early in the season and inspect plants weekly.
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.
