Brilliant Star is grown for ornamental flowers, not harvest. Deadhead spent blooms by pinching or cutting below the faded flower head to encourage continuous blooming throughout the season. Cut flowers for arrangements in early morning when stems are turgid; they last 7-10 days in a vase.
Fun Facts
- 🌱 Gaillardia gets its common name 'blanket flower' because the petals resemble the blankets created by Native American tribes, and it grows in colorful masses like woven blankets across prairies.
- 🌱 Brilliant Star can bloom continuously for 3-4 months with proper deadheading, and established plants often self-seed, returning year after year with increasingly larger displays.
- 🌱 The genus Gaillardia was named by botanists to honor Gaillard de Marentonnes, an 18th-century French patron of botany and naturalist expeditions.
