Seedling
2-3 weeksTiny seedlings with first true leaves appearing 5-7 days after germination. Very delicate with minimal growth.
Maintain high humidity and consistent moisture. Provide bright indirect light. Keep soil warm (70-75°F). Thin seedlings if overcrowded.
Vegetative
3-4 weeksRapid growth of stems and foliage with bushy branching. Plant develops a compact mounding shape.
Pinch back growing tips at 3-4 inches to encourage bushier growth. Maintain consistent watering and begin light fertilizing every 2 weeks. Ensure plenty of sunlight.
Bud Formation
2-3 weeksVisible flower buds appearing at branch tips. Plant transitions from primarily foliage to flower production.
Continue light pinching if desired for fuller shape. Increase fertilizing to every 10-14 days using balanced or slightly higher phosphorus fertilizer. Maintain consistent watering.
Flowering
10-16 weeks until frostAbundant small trumpet-shaped flowers in colors ranging from white, pink, purple, red, or bicolor. Flowers bloom continuously.
Deadheading is minimal as plant self-cleans. Maintain consistent watering and weekly fertilizing. Remove any diseased foliage promptly. Reduce watering if plants look stressed from too much moisture.
End of Season
Until first frostPlant growth slows and flowering decreases as temperatures cool in fall. Frost kills the tender annual plant.
Harvest seeds if desired before first frost. Plan for spring replanting or propagate from cuttings to overwinter indoors. Remove dead plant material.

Common Pests
-
Spray with insecticidal soap or neem oil weekly. Remove affected leaves. Yellow sticky traps. Improve air circulation.
-
Increase humidity and mist foliage. Spray with water to dislodge. Use insecticidal soap or miticide if severe. Avoid over-fertilizing with nitrogen.
-
Allow soil surface to dry slightly between waterings. Use sand layer on top of soil. Yellow sticky traps. Ensure proper drainage.
-
Spray with strong water stream to dislodge. Use insecticidal soap. Apply neem oil every 7-10 days if needed.

Container and hanging basket gardening
HouseholdThe compact mounding habit and continuous flowering make Easter Bonnet ideal for containers, hanging baskets, window boxes, and mixed plantings. Its trailing stems cascade beautifully over pot edges. [source]
Cut flower arrangements

Pollinator attraction
WildlifeEaster Bonnet flowers attract butterflies, bees, and other pollinators with their abundant nectar and pollen production throughout the season. [source]
Landscape edging and borders
HouseholdThe plant's low, spreading growth habit makes it excellent for edging garden beds, creating color borders, and softening landscape hardscapes. [source]
Harvest Tips
Easter Bonnet is grown for continuous ornamental flower display rather than harvest. Deadheading is optional as the plant readily self-cleans spent blooms. For seed collection, allow a few flowers to fade and set seed pods, then harvest brown seed pods before frost. For propagation, take softwood cuttings in late summer and overwinter indoors under grow lights.
Fun Facts
- 🌱 Easter Bonnet is a cultivar of calibrachoa, which are related to but distinct from petunias—calibrachoas have smaller flowers and are often called 'million bells' because of their prolific blooming.
- 🌱 The plant was developed through hybrid breeding to emphasize compact, mounding growth and self-cleaning flower characteristics, making it low-maintenance for gardeners.
- 🌱 Calibrachoas produce tiny seeds (about 5,000 per gram) that require light to germinate, which is why they cannot be covered with soil when sowing.
