About Gazania
The Gazania, scientifically known as Gazania rigens and affectionately called the Treasure Flower or African Daisy, is a dazzling low-growing perennial belonging to the Asteraceae family. Native to the sandy dunes and sunny grassy banks of South Africa, Mozambique, and Namibia, this hardy plant has become a global favorite for dry, sun-drenched landscapes. It grows as a compact, sprawling groundcover that forms a dense, evergreen mat of foliage, which erupts into a spectacular carpet of brilliant composite blossoms from early spring until the first autumn frosts.
Gazanias are characterized by their striking, daisy-like flower heads that measure 2 to 4 inches across, sitting on short, sturdy stems just above the foliage canopy. Each bloom features a central disc of tiny, dense tubular florets surrounded by a radiating ring of broad, petal-like ray florets. These 'petals' display a stunning range of colors—including neon yellow, fiery orange, bronze, pink, and rich mahogany—often decorated with a darker, contrasting band or ring of black, bronze, or purple at the base, creating a dramatic 'halo' effect. The foliage consists of narrow, lanceolate leaves that are a glossy, dark green on the upper surface with a contrasting, woolly, silvery-white underside.
As a member of the sunflower family, the Gazania's floral structure is represented by the formula ⊕ ⚥ (Disc) / % ♀ (Ray) K(pappus) C(5) A(5) G(2). This composite structure consists of two distinct floret types. The central disc florets are actinomorphic (radially symmetrical) and bisexual (⚥), featuring 5 fused petals, 5 fused anthers forming a tube, and a 2-carpellate inferior ovary. The outer ray florets are zygomorphic (bilaterally symmetrical) and typically female (♀) or sterile, serving primarily to attract pollinators to the flower head.
These treasure flowers are the ultimate low-maintenance plants, thriving in USDA zones 8 through 11 as perennials, and frequently cultivated as warm-season annuals in colder climates. They require full sun to perform, as their blooms exhibit a fascinating behavior called nyctinasty—closing tight at night and on cloudy days, only opening to show their true colors under clear, direct sunlight. They prefer light, sandy, or gravelly, exceptionally well-draining soil and are highly drought-tolerant, requiring minimal water once established, though they can suffer from crown rot if overwatered.
The genus name honors Theodore of Gaza, a 15th-century Greek scholar who translated influential botanical works from Greek to Latin, while the common name 'Treasure Flower' refers to the plant's bright, coin-like golden colors. In Indian regional languages, it is known as गज़ानिया (Gajania) in Hindi and Nidhi Puvvu in Telugu, which literally translates to 'treasure flower.' Culturally, they have come to represent wealth, radiant beauty, and the warm, joyful energy of the midday sun.
From a safety standpoint, Gazania is a wonderful choice for pet-owning gardeners. It is completely NON-TOXIC to cats, dogs, and horses, making it an excellent, worry-free choice for rock gardens, borders, and seaside container displays. Curious pets can sniff and explore around these low-growing mats without any risk of poisoning.

Gazanias are often confused with other South African daisies, particularly Cape Daisies (Osteospermum) or common marigolds (Tagetes). They are easily distinguished by their low-growing, trailing habit, their uniquely banded petals, and the distinctive woolly, silvery-white undersides of their narrow leaves, which are absent in Osteospermum. They serve as an exceptional groundcover alongside taller ornamentals; we suggest pairing them with Poinsettia or English Marigold. Check our Flower Identifier to discover more Asteraceae varieties.

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.
