Gaillardia
伊東 春乃

Gaillardia, also known as blanket flower, is a member of the Asteraceae family, native to North America. Its vivid bicolor blooms in shades of red, orange, and yellow and its long blooming period from early summer to late autumn have made it a favorite in gardens around the world.

This article provides a detailed look at Gaillardia’s botanical traits, its cultural and historical background, and practical care advice.

Basic Information

  • Scientific nameGaillardia
  • Family: Asteraceae
  • Origin: North America (including the United States, southern Canada, and Mexico)
  • Appearance: Most flowers feature a red or reddish-brown center surrounded by yellow or orange petals. The blooms, which may be single or double, measure 5–10 cm in diameter. The narrow leaves are lightly hairy.
  • Blooming season: From early summer (around June) to late autumn (around November), depending on climate and care.

Cultural Significance Around the World

In North America, Gaillardia is widely known as “blanket flower.” The name refers to the resemblance between the flower’s bold colors and traditional Native American woven blankets. Among tribes such as the Navajo and Hopi, vivid patterns and color palettes were deeply embedded in daily life and material culture, and this association contributed to the flower’s common name.

In Europe, Gaillardia was introduced as a garden plant in the 19th century. Its drought tolerance made it especially valuable for rock gardens and naturalistic landscaping. In Germany and the Netherlands, it became popular in xeriscaping and dry garden designs. More recently, in the UK, it has gained attention in wildflower-inspired gardens and sustainable planting schemes.

Historical Background

The genus Gaillardia was named in honor of Gaillard de Charentonneau, an 18th-century French magistrate and passionate plant enthusiast. Wild species of Gaillardia were brought from North America to Europe in the late 18th and early 19th centuries, where selective breeding began to enhance their ornamental appeal.

During the Victorian era, particularly in Britain, Gaillardia became a popular summer and autumn bedding plant. Breeding programs expanded the range of flower colors and forms, giving rise to the rich diversity of cultivars we see today. In early 20th-century America, some wild species of Gaillardia were even recognized in national parks as part of native flora conservation efforts.

Gardening Advice

Gaillardia is a relatively easy plant to grow and can thrive when basic conditions are met. Below are some key care guidelines:

Sunlight

Choose a spot with full sun exposure. Gaillardia grows best with plenty of direct light, and inadequate sunlight may reduce blooming.

Watering

Allow the top layer of soil to dry out before watering. While Gaillardia is tolerant of dry conditions, excessively wet soil can cause root rot. Water more frequently during prolonged heat or drought.

Soil

Use well-draining soil such as sandy or loamy soil. For container planting, a commercial potting mix supplemented with perlite or coarse sand will improve drainage and root health.

Fertilizer

Apply a balanced, slow-release fertilizer in spring. Excessive feeding can lead to leggy growth and fewer flowers, so fertilize sparingly.

Deadheading and Pruning

Remove spent flowers regularly to promote continuous blooming. In late autumn, cut the stems back to the base to prepare the plant for the next season.

Overwintering

Annual varieties will die back in fall. Perennial types can overwinter in the ground in warmer climates. In colder areas, provide winter protection such as mulching, or bring pots indoors.

Conclusion

Originally found in the wild landscapes of North America, Gaillardia was introduced to European horticulture in the late 18th century. Its colorful flowers and extended blooming period quickly made it a staple in summer and autumn gardens worldwide.

With its unique historical and cultural background, Gaillardia serves not only as a beautiful garden plant but also as a symbol of botanical exchange between continents. When given suitable conditions, it can brighten both flower beds and container gardens throughout the warmer months.
