Growth Stages

1

Seedling

2-3 weeks

Tiny seedlings with first true leaves emerging; very delicate and pale green

Keep soil consistently moist under grow lights or bright indirect light. Maintain 70-75°F temperature. Avoid damping off with good air circulation.

2

Vegetative Growth

2-4 weeks

Plant develops trailing stems with small oval leaves; no flowers yet

Transplant to larger containers once true leaves appear. Provide bright light and maintain moisture. Pinch growing tips to encourage bushier growth if desired.

3

Pre-Flowering

1-2 weeks

Stems elongate significantly; leaf nodes thicken and buds begin forming at branch tips

Begin light fertilizing with balanced or slightly phosphorus-rich fertilizer. Ensure adequate light and warmth. Harden off seedlings before outdoor planting.

4

Flowering & Blooming

8-12+ weeks (through frost in cool climates)

Abundant delicate lilac fan-shaped flowers (5 petals arranged asymmetrically) cover the plant; continuous blooms throughout season

Deadhead spent flowers to encourage more blooms. Water regularly and feed every 2-3 weeks with balanced fertilizer. Provide full sun for maximum flowering.

5

End of Season

Varies by climate

In frost-prone areas, plant declines after first freezes; in warm zones, may slow flowering in winter

In zones 9b and warmer, reduce watering and allow plant to rest. In cooler zones, plan to replace annual plants. Can save cuttings indoors over winter for next season.

Fun Facts

  • 🌱 The name 'Scaevola' comes from the Latin word meaning 'left-handed,' referring to the fan-shaped flowers that have petals arranged asymmetrically only on one side of the bloom—a unique characteristic among garden flowers.
  • 🌱 Fan Flower is native to Australia and is surprisingly drought-tolerant once established, making it an excellent choice for water-conscious gardeners in hot climates.
  • 🌱 The variety 'Lilac' is part of the Scaevola aemula species, which has produced numerous color cultivars in white, purple, pink, and blue, all with the same distinctive fan-flower shape.
