Seedling
2-3 weeksTiny seedlings emerge with narrow cotyledons and develop the first true leaves within 1-2 weeks. Plants are delicate and pale green.
Keep soil consistently moist but not waterlogged. Provide bright light. Thin seedlings to proper spacing once they have 2-3 true leaves.
Vegetative
3-4 weeksPlants develop bushy, compact growth with narrow, lance-shaped blue-green foliage. Multiple stems form from the base, creating a mounding habit.
Water regularly and maintain good air circulation. Pinch growing tips early to encourage branching. Apply balanced fertilizer every 2-3 weeks.
Budding & Flowering
6-12 weeks or until frostFlower buds appear at stem tips, developing into vibrant pink blooms with distinctive darker pink or magenta centers. Flowers are typically double and sweetly scented.
Maintain steady moisture. Deadhead spent flowers regularly to encourage continuous blooming. Increase phosphorus-rich fertilizer to support flower production.
Peak Bloom
4-8 weeksPlant reaches maximum floral display with numerous pink flowers covering the compact mound. Blooms remain prolific with consistent deadheading.
Continue deadheading daily for best display. Water deeply and regularly during hot periods. Watch for pests and fungal issues in humid conditions.
Late Season & Decline
Until frost or excessive heatAs temperatures cool (in fall) or heat intensifies (in summer), flowering may slow. In mild climates, plants may persist into late fall or winter.
Reduce deadheading and allow some flowers to set seed if you want self-seeding. Reduce watering in cool months. Consider removing or replacing plants if flowering stops.

Harvest Tips
Firefly Pink is grown primarily for ornamental display rather than harvest. Cut flowers in early morning when fully open for indoor arrangements; they have good vase life (7-10 days). Deadhead spent blooms regularly by pinching off flowers just below the calyx to promote continuous flowering throughout the season. Allow a few flowers to remain in late season if you want plants to self-seed for next year.
