How to Grow Gazanias
Gazania flowers are for any gardener who is looking for a high-impact bloom that doesn't require much maintenance. Gazania plants don’t mind the heat that radiates off the pavement, so you can include them in your sidewalk garden or alongside your driveway.

Plant young gazania plants about a foot apart, allowing them to reach their eventual spread of 10 inches without crowding, which promotes mildew. Deadhead gazania flowers to extend the blooming time of the plants.
Gazania flowers thrive in full sun. Morning or afternoon shade may cause the flowers to stay closed for a portion of the day and may cause the plants to grow lanky, exceeding their normal height of 6 to 10 inches.
Gazanias do best in sandy, well-draining soil but will tolerate many soil types and conditions.
The leathery foliage of gazania plants is a clue to the high drought tolerance of this flower. Let the soil dry between waterings. Overwatering can lead to root rot and promote fungal diseases.
Temperature and Humidity
In their native habitat of the rocky cliffs of South Africa, gazanias grow in soils of low fertility. Compost and supplemental fertilizer aren’t necessary.
Potting and Repotting
Gazania plants are adaptable enough to overwinter indoors so you won’t need to purchase new plants or seeds for the next growing season. You can dig up the plant at autumn's end while they are still in bloom, bringing the beauty of the outdoors in. However, the plant won't be able to maintain its flower output indoors, so cut the plant back and keep it in a cool, sunny window. Water when the soil surface is dry. Check the plants regularly for pests like mealybugs that may proliferate on indoor specimens.
The daisy-like flowers blooms of gazanias often come in a variety of hot hues on the color wheel, like red, orange, and yellow. Many flowers feature solids and horizontal or vertical variegation on petals, sometimes with splashes of white and bright pink.
Gardeners who live in areas with short growing seasons should try gazanias from the Chansonette series, which flower very early. Love the classic look of white flower gardens? The Creamsicle gazania cultivar sports ivory petals with a simple bronze center disk. Another early performer is the Daybreak series, which yields large flowers quickly from seed in sunset colors or stripes.

The monochromatic gold petals and disks of Sundrop gazanias will bring a ray of sunshine to any flower garden.

Growing in Containers
Gazanias shine in containers on your deck or patio, where they will attract butterflies for up-close observation. If desired, plant gazanias at the edge of the pot so their trailing habit softens the container's edges. Their preference for sharply drained soil makes them a natural choice for a rock garden, either in a container or on the ground. If your soil is heavy, plant your gazanias in containers with a companion planting of lantana, which has similar growing conditions and complementary colors.
Growing From Seeds
If you grow your gazania flowers from seed, start them indoors about 10 weeks before the last frost in your area. Cover the seeds with a thin layer of soil and keep them moist throughout the germination and transplant stage. Harden them off and set them outdoors two weeks after the average last frost.
If you prefer no-fuss seed starting, try sowing gazania seeds directly in the garden. After all danger of frost has passed, sprinkle the seeds in an area of raked soil. Scatter handfuls of soil to cover the seeds, as darkness helps to trigger germination.
