Seedling
7-10 daysTiny seedlings with first true leaves appearing; very small and delicate
Keep soil moist under bright light; maintain 70-75°F; provide good air circulation to prevent damping off; avoid burying seeds
Vegetative Growth
3-4 weeksRapid stem and leaf development; plant becomes bushy and spreads outward; no flowers yet
Maintain full sun exposure; pinch growing tips once or twice to encourage branching; keep soil consistently moist; fertilize every 1-2 weeks with balanced or slightly lower-nitrogen fertilizer
Bud Formation
1-2 weeksSmall flower buds begin forming along leaf axils and stem tips
Continue regular fertilizing; maintain consistent watering; ensure full sun; buds should appear readily on healthy plants
Flowering
8-12 weeks or until frostAbundant small pink flowers open continuously from late spring through frost; flowers are 1-1.5 inches diameter
Deadheading is optional as cultivar is self-cleaning; continue regular watering and fertilizing every 1-2 weeks; pinch back overly long stems to maintain shape; watch for spider mites in heat stress
Decline/End of Season
2-4 weeksIn zones 3-9, plant declines as temperatures drop below 50°F; flowers become sparse and smaller
In cold zones, discard plant before first frost or bring containers indoors. In warm zones, can cut back and overwinter as perennial for next season

Pollinator Support
WildlifeFlowers attract butterflies, bees, and hummingbirds, providing nectar throughout the growing season. Ideal for supporting pollinator populations in gardens. [source]
Harvest Tips
Not harvested for crop—enjoyed for continuous flowers. Pinch off spent flower clusters occasionally to encourage fuller branching, though variety is largely self-cleaning. Cut stems for fresh arrangements as desired throughout the season.
Fun Facts
- 🌱 Summer Wave Pink is part of the Calibrachoa genus, which produces the smallest flowers among petunia relatives—each bloom is typically under 1.5 inches across.
- 🌱 The 'Summer Wave' series was specifically bred for continuous flowering with minimal deadheading, making it far more low-maintenance than traditional petunias.
- 🌱 Despite being called a petunia relative, calibrachoas are actually in the same plant family (Solanaceae) but are distinct species; they naturally occur in South America.
