Bloom Time: Summer
Gazania rigens is a tender perennial that features decumbent stems that spread along the ground. Narrow but variably-shaped, dandelion-like leaves (narrow, spoon-shaped to lobed) are silvery green. Flowering stems typically rise to 10 inches (25 cm) tall, topped by solitary, daisy-like ray flowers up to 4 inches (10 cm) wide, with contrasting center disks. Ray flowers are brilliant yellow to orange with black eyes at the bases and with orange-brown disks. Can bloom summer to fall, often to the first frost. Flowers close at night and may only partially open up on cloudy days.
How to Grow and Care
Plant Gazanias in early spring, in full sun and well-draining soil, spacing multiple plants 12 to 18 inches (30 to 45 cm) apart to form a ground cover mat. These flowers can tolerate almost any type of soil — alkaline, acidic, loam, clay, and sand — as long as they have good drainage, though they prefer good, fertile loam.
Water the Gazania, keeping it moist after planting until you see new growth. Once growing on its own, this plant is quite a drought-tolerant, and only requires supplemental water during droughts of three weeks or more. Water in the morning, as Gazanias can succumb to stem and root rots, powdery mildew and leaf spot that can result from staying wet for too long.
Pinch off fading flowers with your fingers to encourage a more extended bloom period. Prune annually in late winter or early spring, beginning in the second season, cutting the foliage back to 2 or 3 inches above the ground with pruning shears. This will refresh the plant and encourage new growth. See more at How to Grow and Care for Gazania.
