Seedling
2-3 weeksTiny seedlings with first true leaves appearing; very delicate with fine foliage.
Keep soil moist but not soggy. Provide bright light (grow lights 3-4 inches above seedlings). Maintain 70-75°F. Avoid damping-off by ensuring good air circulation.
Vegetative Growth
3-4 weeksPlant develops branching stems with narrow, finely-textured foliage; no blooms yet but rapid stem elongation.
Pinch back tips when 4-6 inches tall to encourage bushier growth and more branches. Maintain consistent moisture and warmth (65-75°F minimum). Begin light feeding with balanced fertilizer.
Budding
1-2 weeksSmall fan-shaped flower buds appear at stem tips; foliage becomes denser and more established.
Increase phosphorus-rich fertilizer (higher middle number) to support flowering. Maintain full sun exposure. Continue regular watering without overwatering.
Flowering
8-12 weeks (extends with proper care)Abundant delicate fan-shaped flowers open in clusters at stem tips; plant may cascade 12-24 inches depending on variety and conditions.
Deadhead spent flowers to encourage continuous blooming (though self-cleaning). Feed every 2 weeks with diluted balanced or bloom fertilizer. Water consistently; drought stress reduces flowering.
Decline/Winter Dormancy
Variable; depends on climate and whether plant is overwinteredFlowering slows in fall and winter; foliage may become sparse if temperatures drop below 50°F.
Reduce watering as growth slows. Move indoors or to frost-free location in zones below 9b. Prune back by one-third to rejuvenate. Minimal fertilization needed.

Fun Facts
- 🌱 The name 'fan flower' derives from the distinctive fan or wheel-shaped blooms, which have one larger petal and four smaller petals arranged in a unique asymmetrical pattern.
- 🌱 Scaevola is native to Australia and has become a cornerstone plant in the ornamental horticulture industry since its introduction to cultivation in the 1980s.
- 🌱 Unlike many annuals, fan flower requires very little deadheading as it continuously sheds spent flowers and produces new blooms, earning it the reputation of being 'self-cleaning'.
