Germination & Seedling
2-3 weeksTiny seedlings emerge with true leaves developing within 2-3 weeks. Plants are delicate and light-dependent.
Keep soil moist but not waterlogged. Provide bright light. Do not cover seeds; light aids germination. Thin seedlings to proper spacing.
Vegetative Growth
4-6 weeksLow rosette of narrow, lance-shaped leaves develops. Plant builds root system and foliage in first season.
Maintain consistent moisture. Apply organic mulch around plants. Remove any competing weeds. Begin fertilizing with diluted balanced fertilizer every 3-4 weeks.
Budding & Flowering
4-6 weeksSlender stems extend 18-24 inches tall with terminal clusters of distinctive fringed flowers ranging from bright pink to red-pink. Buds form at stem tips.
Deadhead spent flowers to encourage prolonged blooming. Stake tall or floppy stems if needed. Continue regular watering. Fertilize every 2-3 weeks with lower nitrogen formula.
Peak Bloom & Self-Seeding
2-4 weeksFlowers reach maximum color and abundance. Blooms attract insects. Late flowers begin setting seed if not deadheaded.
Leave some flowers on plant if you want self-seeding. Continue deadheading for continuous blooms. Water during hot, dry weather.
Seed Production & Senescence
6-8 weeksFlowers fade to seed pods. Foliage may decline as plant enters dormancy. Seeds ripen and scatter.
Allow some seed heads to mature and drop naturally for next year's plants. Cut back dead foliage in late fall or early spring. Tidy plant for winter appearance.
