Growth Stages

Seedling

2-3 weeks

Tiny seedlings with first true leaves emerging; very delicate and prone to damping off

Keep soil moist but not wet. Provide bright light without direct sun initially. Ensure excellent air circulation. Avoid cold temperatures below 50°F.

Vegetative Growth

3-4 weeks

Plant develops trailing stems with small oval leaves; compact branching structure forms

Pinch back growing tips to encourage bushier, more compact growth. Maintain consistent moisture. Begin light feeding with balanced fertilizer every 2 weeks.

Flowering

8-12+ weeks (continuous if conditions are favorable)

Small, delicate fan-shaped blue flowers with darker purple markings appear at stem tips; prolific blooming begins

Switch to higher phosphorus fertilizer to promote blooms. Remove spent flowers occasionally, though deadheading is not essential. Maintain steady moisture and good drainage.

Peak Production

4-6+ weeks

Dense cascading growth completely covered with blue flowers; long trailing stems extend 12-24 inches

Maintain regular watering schedule. Feed every 2-3 weeks. Prune back if growth becomes too leggy. Ensure good air circulation to prevent fungal issues.

Decline (End of Season)

Varies by climate

Flowering slows as temperatures cool or daylight decreases; growth may become sparse

Cut back plant if overwintering as perennial in frost-free areas. Remove from garden in frost-prone zones. Store cuttings for propagation if desired.

Fun Facts

🌱 Scaevola means 'left-handed' in Latin, referring to the asymmetrical, fan-shaped flowers that appear to face one direction.
🌱 The 'Blue Wonder' cultivar produces flowers more abundantly and consistently than many other scaevola varieties, with minimal deadheading required.
🌱 Despite thriving in hot, sunny conditions, Trailing Scaevola has high salt tolerance, making it suitable for coastal gardens and areas with poor water quality.
