When to plant
spring
Overwintering
In colder climates, treat them as annuals or bring containers indoors to a sunny, cool spot. Keep the soil on the drier side during the winter months to prevent rot.
In containers
They grow very well in containers, provided the pot has excellent drainage and is at least 8 inches deep.

Seed Sowing

  1. Sow seeds in a well draining seed starting mix in early spring.
  2. Cover lightly with soil and keep in a warm, bright location.
  3. Transplant seedlings once they have two sets of true leaves.

Basal Cuttings

  1. Take cuttings from non flowering basal shoots in late summer.
  2. Remove lower leaves and dip the cut end in rooting hormone.
  3. Place in a gritty, well draining medium until roots develop.

Group plants with similar drought tolerance to ensure they all thrive without overwatering the sun lovers.

Bonnes associations

  • Lavender They share similar needs for full sun and well drained soil.
  • Blue Fescue The blue foliage of the grass contrasts beautifully with the bright Gazania blooms.
  • Sedum Both plants are drought tolerant and thrive in similar sunny conditions.

À éloigner de

  • Hostas Hostas require shade and more moisture, which would lead to rot for the Gazania.

Espèces similaires

  • Osteospermum They are both members of the Asteraceae family and share similar growth habits.

Ce qu'on demande souvent

Why are my Gazania flowers closed?
They likely need more direct sunlight or it is currently night time.
Do I need to deadhead them?
Removing spent blooms encourages the plant to produce more flowers throughout the season.

D'où vient le nom

The genus is named after Theodorus of Gaza, a 15th century scholar who translated botanical works. The species name rigens refers to the stiff or rigid nature of the leaves.

Bon à savoir

  • Gazanias are often called treasure flowers because of their vibrant, jewel like colors.
  • They are native to Southern Africa and thrive in sandy, well drained soils.
  • The flowers only open fully in bright, direct sunlight.
