Seedling
2-3 weeksTiny seedlings with two rounded cotyledons emerge within 7-14 days. First true leaves appear shortly after and are narrow and lance-shaped.
Keep soil moist but not waterlogged. Provide bright light (14-16 hours daily under grow lights). Maintain temperatures of 70-75°F.
Vegetative Growth
3-4 weeksPlant develops bushy growth with multiple stems and narrow green leaves. No flowers yet; focus is on establishing roots and foliage.
Pinch back growing tips when seedling is 4-6 inches tall to encourage branching. Gradually acclimate to outdoor conditions if growing indoors.
Budding
2-3 weeksSmall flower buds form at the tips of stems. Plant continues vegetative growth while buds develop.
Ensure consistent moisture and full sun. Begin light fertilizing with balanced fertilizer every 2 weeks.
Flowering
12-16 weeks (spring through fall)Vibrant neon pink flowers with dark purple/magenta eyes open in succession. Plant is heavily covered in blooms.
Deadhead spent flowers to encourage continuous blooming. Maintain regular watering and weekly fertilizing with bloom-boosting fertilizer (higher phosphorus).
Decline/End of Season
4-8 weeks depending on climateIn fall as temperatures cool, flowering slows and plant may stop blooming. Growth becomes sparse.
In zones 2-8, plant will decline with frost. In warmer zones, may persist as perennial; cut back in early spring for renewal.
