Double Sunset Gaillardia is an antique variety with roots reaching back to at least 1886, revived from the archives of heirloom gardening. This native North American wildflower produces an almost otherworldly display of quilled single and double petals in mixed, sunset-inspired colors that seem to glow in full sun. Heat-tolerant and a relentless bloomer throughout the season, it thrives in zones that support 60-90°F temperatures and spreads 12 inches wide, making it equally stunning in borders or scattered freely across wild gardens. Cut a bouquet and you'll discover why seed savers have kept this variety alive for over a century.

The petals on Double Sunset are architectural marvels, quilled and ruffled in ways that catch light like no smooth-petaled gaillardia can. This is the variety that made collectors and gardeners in the 1880s stop and stare, and the reason it's still grown today. You'll get continuous color from spring through frost, even when other flowers have given up, because heat and long blooming seasons are literally what this plant does best. As a native wildflower that also cuts like a dream, it works equally well scattered through a meadow or brought indoors to a vase.
Double Sunset Gaillardia is grown primarily for its ornamental appeal and as a cut flower. The quilled, double petals and mixed warm tones make bouquets and arrangements, while the plant's role as a pollinator-friendly native wildflower means gardeners plant it to support bees, butterflies, and other beneficial insects. It's equally at home massed in flower borders for continuous summer color or allowed to freely self-sow in wild areas where it can establish itself as part of the natural landscape.

You can start Double Sunset indoors 6-8 weeks before your last spring frost. Sow seeds directly on the surface or press them gently into seed-starting mix at a depth of 1/8 to 1/4 inch. Keep the soil warm and moist at 60-90°F. Seedlings will emerge in 14-21 days. Harden them off gradually before transplanting outdoors after the last frost date has passed.
Transplant seedlings outdoors after the last frost date when soil has warmed and nighttime temperatures stay above 50°F. Space plants 12 inches apart. Water gently at transplanting and keep soil evenly moist for the first two weeks while plants establish roots.
Direct sow seeds where you want them to grow after the last frost date, or scatter seeds in fall for spring germination. Press seeds lightly into the soil at a depth of 1/8 to 1/4 inch. Keep the area lightly watered until seedlings emerge in 14-21 days. Thin seedlings to 12 inches apart once they have their first true leaves.
For cut flowers, harvest in the morning after dew dries but before the heat of the day. Cut stems at least 6 inches long, choosing blooms that are fully open but still crisp. Remove lower foliage before arranging. Double Sunset flowers continue opening over several days in the vase, and the quilled petals hold their shape beautifully for a week or more.
Deadhead spent blooms throughout the season to encourage continuous flowering and a bushier plant shape. If you want self-sown seedlings the following year, allow some flowers to mature and drop seed toward the end of the season. No hard pruning is necessary, but you can cut plants back by one-third in midsummer if they become leggy.

“Double Sunset Gaillardia emerges from America's prairie heritage, a native wildflower that gardeners began selecting for double flowers and intensified coloring in the 1800s. By 1886, this variety had already become established and documented enough to earn a place in seed catalogs, where it remained a fixture for generations. The fact that it survives today as an heirloom speaks to gardeners who saved seed year after year, valuing its combination of native toughness and theatrical beauty. This is a flower that traveled from wild prairie to Victorian garden beds and back again, each generation recognizing something worth preserving.”
