About Gaillardia
Gaillardia, botanically classified within the genus Gaillardia in the Asteraceae (sunflower) family and popularly known as the Blanket Flower or Indian Blanket, is a group of exceptionally cheerful, sun-loving annuals and short-lived perennials. Native to the dry prairies, sandy plains, and pine barrens of North and South America, this highly resilient wildflower has captured the hearts of gardeners worldwide. Celebrated for its daisy-like blossoms painted in bold, blazing concentric bands of red, orange, and yellow, it stands as a premier choice for high-impact summer borders.
Growing in multi-stemmed, bushy mounds that reach 1 to 3 feet in height and spread up to 18 inches, Gaillardia is characterized by its rough, hairy, grey-green lanceolate leaves. From early summer through first frost (June to October), the plant produces an endless profusion of solitary composite flower heads measuring 2 to 4 inches across. The ray florets feature a distinctive three-toothed flared tip, displaying bold, bicolor patterns of crimson-red bases with bright golden-yellow margins, surrounding a dark burgundy-purple central disc.
The reproductive architecture of the Blanket Flower capitulum is represented by the botanical floral formulas: Ray florets: Br % ♀/⚥ K0 C∞ A0 G(2) ; Disc florets: Br ⊕ ⚥ K0 C(5) A(5) G(2). This formula indicates that the outer ray florets are female or sterile, zygomorphic, and have 3-lobed petals with no stamens. The central disc florets are bisexual, actinomorphic, and tubular, featuring 5 fused petals, 5 stamens with fused anthers, and a syncarpous gynoecium composed of 2 fused carpels with an inferior ovary.
Horticulturally, Gaillardia is an incredibly tough, low-maintenance plant that thrives on neglect. It requires full, intense, direct sunlight, needing a minimum of 6 to 8 hours of direct daily exposure to produce its massive flush of blooms. It demands poor, sandy, rocky, or gravelly soils with exceptional drainage; planting it in rich, fertile, or highly fertilized soils will cause weak, floppy growth and significantly shorten its lifespan. Once established, it is extremely drought and heat tolerant across USDA zones 3 through 10.
The genus name Gaillardia honors Gaillard de Charentonneau, an influential 18th-century French magistrate and patron of botanical research. The common name 'Blanket Flower' was inspired by the striking, warm color patterns of the blossoms, which closely resemble the traditional hand-woven wool blankets of Native American tribes. Famed on the Indian subcontinent as Blanket Flower (ब्लांकेट फ्लावर) and in classical Sanskrit as Bahuvarnapushpam (बहुवर्णपुष्पम्), it serves as a symbol of bright optimism, warmth, and resilience.
For pet-owning families, the Blanket Flower is a safe and joyful landscaping choice. Gaillardia species are classified as completely NON-TOXIC to cats, dogs, and horses by leading veterinary safety databases, including the ASPCA. While the fine hairs on the leaves can occasionally cause a mild, mechanical skin irritation (contact dermatitis) if dogs brush against them heavily, the plant contains no toxic systemic chemicals.

Blanket Flower is occasionally confused with wild Sunflowers (Helianthus) or Marigolds (Tagetes). It is easily distinguished because Gaillardia features three-toothed tips on its ray petals and distinctive burgundy-burgundy centers, whereas marigolds have highly aromatic, deeply dissected leaves and ruffled petals. It pairs beautifully in sunny rock gardens beside other heat-lovers; we suggest planting it with Gazania or low-growing Cigar Flower. Find more sun-loving Asteraceae in our Flower Identifier.

Frequently Asked Questions
What is Floral Formula?
A floral formula is a symbolic representation of a flower's structure using letters, numbers, and special symbols. It provides a concise way to describe the arrangement and number of floral parts.
This formula describes the flower's symmetry, sepals, petals, stamens, and carpels in a standardized format.
Formula Sequence
- Bract: Br or Ebr
- Bracteole: Brl or Ebrl
- Symmetry: % (Radial) or ⊕ (Bilateral)
- Sex: ♀ (Female), ♂ (Male), or ⚥ (Bisexual)
- Calyx/Sepal: K<number> (Free or Fused)
- Corolla/Petal: C<number> (Free or Fused)
- Androecium: A<number> (Free or Fused)
- Gynaecium: G<number> (Superior or Inferior Ovary)
Symbol Meanings
- Numbers: Indicate quantity of parts
- Parentheses (): Parts are fused together
- Plus (+): Parts in different whorls
- Underline: Superior ovary position
- Overline: Inferior ovary position
- ∞: Numerous parts (too many to count)
Understanding floral formulas helps botanists quickly identify and classify flowers based on their structural characteristics.
