1. Basic Identification

Common Name: Treasure Flower, Gazania
Botanical Name: Gazania rigens
Variant: Standard
Plant Color: Multicolor
Plant Country: Unknown
Arabic Name: جازانيا
Stems: 1
Family: Asteraceae

2. Taxonomy & Classification

Gazania rigens belongs to the kingdom Plantae, order Asterales, and family Asteraceae (the daisy family). It is classified under the genus Gazania, which consists of approximately 16 species of low-growing herbs and shrubs known for their vibrant, daisy-like flower heads.

3. Origin & Distribution

The Treasure Flower is native to southern Africa, specifically the Cape Province and KwaZulu-Natal. It has been naturalized in many other warm regions across the globe, including the Mediterranean, parts of Australia, and the southwestern United States, due to its adaptability to coastal and arid environments.

4. Visual Characteristics

This plant features striking, daisy-like flowers that can reach up to 4 inches in diameter. The petals often come in brilliant shades of yellow, orange, red, and bronze, frequently displaying a contrasting dark ring around the central disc. Its foliage is equally attractive, with lance-shaped, leathery leaves that are deep green on top and silvery-grey underneath.

5. Size & Dimensions

Gazania rigens is a low-growing, clumping perennial (often grown as an annual in cooler climates). It typically reaches a height of 15–30 cm (6–12 inches) and spreads roughly 15–30 cm wide, forming a dense groundcover.

6. Light Requirements

Full sun is essential for this plant. The flowers are phototropic, meaning they open in bright sunlight and close at night or during heavily overcast days. To ensure consistent blooming and healthy growth, it should be placed in a spot that receives at least 6 to 8 hours of direct sun daily.

7. Watering Needs

Once established, Gazania is highly drought-tolerant. It prefers infrequent but deep watering. Allow the soil to dry out completely between watering sessions. Overwatering or poorly draining soil can lead to root rot.

8. Soil & Potting

The plant thrives in well-draining, sandy, or loamy soil with a neutral pH. It is particularly well-suited for rocky or poor soils where other plants might struggle. If potting, use a high-quality cactus or succulent mix to ensure adequate drainage.

9. Temperature & Humidity

Treasure Flowers love the heat and are hardy in USDA zones 9–11. While they can tolerate light frost, they are best suited for warm climates. They handle low to moderate humidity well and are excellent for coastal gardens due to their salt tolerance.

10. Fertilization

Gazanias are light feeders. In most garden soils, they require little to no fertilizer. For container-grown plants or very poor soil, a balanced liquid fertilizer applied once every 4–6 weeks during the spring and summer growing season is sufficient.

11. Maintenance & Care Level

Maintenance is very low. The most important task is deadheading, or removing spent flower heads, which encourages the plant to produce more blooms throughout the season. No significant pruning is required other than cleaning up dead foliage in late winter.

12. Growth & Propagation

They are fast growers. Propagation is easily achieved by sowing seeds in early spring or by taking basal cuttings in late summer. In warm climates, they may also spread via self-seeding or by expanding their clumps over time.

13. Common Problems

The most common issue is root rot caused by overwatering or heavy, clay-rich soil. They can occasionally be bothered by snails, slugs, or mealybugs. Powdery mildew may occur if air circulation is poor and humidity is high.

14. Benefits & Uses

Gazania is an excellent choice for groundcover, rock gardens, and hanging baskets. It is effective for erosion control on slopes and is highly salt-tolerant, making it a favorite for seaside landscaping. Additionally, its flowers attract beneficial pollinators like bees and butterflies.

15. Toxicity & Safety

Gazania rigens is generally considered non-toxic to humans, cats, and dogs. However, as with any ornamental plant, it is best to prevent ingestion by curious pets or small children to avoid potential digestive upset.
