Growth Stages

1

Seedling

2-3 weeks

Thin, delicate stems with small linear-lanceolate leaves emerging.

Keep soil lightly moist but not waterlogged. Provide bright light. Thin seedlings to prevent overcrowding.

2

Vegetative Growth

3-4 weeks

Plant develops rosette form with silvery-green foliage and increasingly sturdy stems.

Water moderately and allow soil to dry slightly between waterings. No fertilizer needed if soil is decent; avoid excess nitrogen.

3

Bud Formation

1-2 weeks

Flower buds begin to form on elongated stems above the foliage.

Maintain full sun and consistent watering schedule. You may lightly fertilize with balanced or phosphorus-rich fertilizer.

4

Flowering

8-12 weeks or more

Large daisy-like bright yellow flowers with dark centers and striped petals bloom profusely.

Deadhead spent flowers to encourage continuous blooming. Water at soil level, not on flowers. Keep soil moderately moist.

5

Decline/End of Season

Variable

Blooming slows as temperatures cool (in cool climates) or plant may rest briefly.

In warm zones, gazanias may bloom year-round; in cool zones, reduce watering and allow plant to decline or bring indoors.

Harvest Tips

Gazanias are ornamental flowers meant for visual display in gardens or cut arrangements. Cut stems in the morning when flowers are fully open for longest vase life (typically 5-10 days). Deadhead spent flowers regularly to promote more blooms.

Fun Facts

  • 🌱 Gazanias close their flowers at night and on cloudy days, a behavior called nyctinasty. Sunny Lemon Star is named for its preference for sunny conditions.
  • 🌱 The genus Gazania is native to South Africa and was named after Theodore of Gaza, a 15th-century scholar and translator.
  • 🌱 Gazanias are sometimes called treasure flowers because their closed petals resemble a treasure chest, and they 'open' to reveal their riches in sunlight.
