Growth Stages

1

Seedling

2-3 weeks

Tiny green seedlings with first true leaves appearing within 7-14 days of germination

Keep soil lightly moist but not waterlogged. Provide bright light. Thin seedlings to proper spacing once they have 2-3 true leaves.

2

Vegetative Growth

4-6 weeks

Plants develop bushy foliage with increasingly deep green leaves and sturdy stems

Water moderately during dry spells. Begin reducing water as plant matures. Pinch back growing tips if you want bushier plants.

3

Bud Formation

2-3 weeks

Flower buds appear at stem tips with reddish tinges visible

Maintain consistent (but not wet) soil moisture. Reduce fertilizer to avoid excess foliage at expense of flowers.

4

Flowering

8-12 weeks (or longer with deadheading)

Abundant star-burst pattern flowers in scarlet-red with yellow petal tips and edges blooming from midsummer onward

Deadhead spent flowers regularly to encourage continuous blooming. Do not overwater. Minimal fertilizer needed.

5

Seed Development & Dormancy

4-8 weeks (variable by climate)

Flowers fade and seed heads form; foliage may yellow as plant prepares for winter or enters dormancy

Allow some flowers to set seed for reseeding and wildlife food. Cut back dead foliage in fall or spring. Divide plants every 2-3 years.

💊

Traditional Herbal Use

Harvest Tips

For cut flowers, harvest in early morning when petals are fully open but before peak heat. Cut stems just above a leaf node to encourage branching. Deadhead faded blooms throughout the season to extend flowering. Allow some flowers to remain for seed production if desired. In fall, leave seed heads for wildlife food and winter interest, then cut back in early spring.

Fun Facts

  • 🌱 The common name 'blanket flower' comes from the resemblance of fields of blooming Gaillardia to colorful Native American blankets.
  • 🌱 Starburst Scarlet is a hybrid (Gaillardia × grandiflora) created by crossing two native American wildflower species, making it more vigorous and ornamental than pure species.
  • 🌱 Once established, these plants are so drought-tolerant they thrive in conditions too dry for most other perennials, yet they still attract abundant butterflies and pollinators throughout the growing season.
