The treasure flower (Gazania rigens) is a resilient, low-growing perennial herb native to coastal and dry regions of South Africa. Cherished for its daisy-like blossoms in vivid hues of yellow, orange, bronze, and pink, it forms spreading mats of narrow, dark green foliage that often features a silvery underside. This trailing groundcover is celebrated among gardeners for its rugged constitution and remarkable drought tolerance.
In landscape design and container gardening, the treasure flower excels in rock gardens, coastal borders, and sunny balcony planters where other plants might wither under intense heat. Its blooming cycle runs from mid-spring until the first autumn frosts in temperate zones. A captivating trait of this plant is its heliotropic habit: the flowers open fully only when struck by direct sun, closing promptly as evening falls or during overcast weather.
Cultivating treasure flowers requires little effort provided they receive uninterrupted sunlight and sharp soil drainage. They naturally tolerate sandy soils, high summer heat, and salty coastal breezes with remarkable ease. By routinely removing spent flower stems, you encourage a steady flush of vibrant new buds that will brighten garden beds throughout the warm season.
Did you know?Its daisy-like blooms respond directly to sunlight, opening wide during sunny hours and closing tightly on cloudy days and at dusk.
Care
- Watering
- Water thoroughly only when the soil has completely dried out, typically every 4 to 5 days in peak summer and every couple of weeks in winter. Always check soil dryness beneath the surface before watering, as standing moisture quickly triggers root rot.
- Light
- Provide full, unobstructed sunlight for at least six hours daily to encourage continuous flowering. In shaded spots, the plant will survive but its flowers will fail to open properly.
- Temperature
- Ideal growing temperatures range between 18 °C and 28 °C during the active season. The plant can withstand brief, light freezes down to -2 °C in dry soil, though severe frost will kill foliage.
- Soil
- Plant in lean, sandy, fast-draining soil mix to prevent water retention around the crown. A standard potting soil amended with ample perlite or coarse grit works best.
- Fertilizer
- Feed monthly throughout spring and summer with a diluted, bloom-boosting liquid fertilizer. Avoid fertilizers high in nitrogen, which stimulate excessive foliage at the expense of blossoms.
- Pruning
- Snip off faded flowers at the base of their stems to stimulate continuous bud production. In early spring, trim back any straggly or frost-damaged stems to rejuvenate the foliage.
- Propagation
- Easily propagate by sowing seeds indoors in late winter under warm, bright conditions. You can also take basal cuttings in late summer to overwinter new plants indoors.

Frequently asked questions
Why are my treasure flower blossoms not opening?
Treasure flowers require direct sunlight to unfold their petals fully each day. During overcast, rainy, or shaded conditions, the blossoms naturally stay closed until bright sunshine returns.
Is Gazania rigens an annual or a perennial?
It grows as a tender perennial in warm, frost-free climates and can persist for multiple seasons. In regions with harsh freezing winters, it is typically grown as an annual bedding plant.
How do I prevent crown and root rot in my plant?
Ensure the plant is set in highly porous, sandy soil with drainage holes and allow the mix to dry completely between waterings. Avoid wetting the center of the foliage rosette when applying water.
Can treasure flowers survive severe drought?
Yes, treasure flowers are exceptionally drought-tolerant once established in garden beds or containers. They perform best with deep, infrequent waterings rather than constant moisture.
