About this plant
Celosia 'Pink Fan' is an ornamental flowering plant prized for its distinctive fan-shaped, velvety pink flower heads that add texture and colour to garden beds and cut-flower arrangements. Gardeners grow it for its long blooming season, upright habit, and ability to thrive in hot, sunny conditions with minimal maintenance.
Germination
Sow seeds indoors 6–8 weeks before the last spring frost at soil temperatures of 21–24°C (70–75°F). Seeds germinate in 7–14 days and require light to sprout, so press seeds onto moist seed-starting mix without covering. Keep soil consistently moist but not waterlogged until seedlings emerge.
How to plant
Sow celosia seeds 6-8 weeks before your average last frost date. Celosia seeds need light to germinate, so sow them on the surface of the soil and lightly cover them.
Growing tips
Plant seedlings outdoors after all frost danger has passed in a sunny location with well-draining soil. Water regularly during establishment, then reduce frequency once plants are mature; Celosia tolerates drought better than wet feet. Fertilize monthly with a balanced or slightly lower-nitrogen formula to encourage flowering over leaf growth. Deadhead spent flower heads to promote continuous blooming throughout summer and autumn. Tall varieties may benefit from staking in windy locations. Watch for spider mites in hot, dry conditions and powdery mildew in humid weather; improve air circulation and avoid overhead watering if humidity is high.
Harvesting
Cut flower heads for arrangements when fully developed and colour is rich, ideally in early morning. Celosia blooms continuously from midsummer until frost, so harvest regularly to extend flowering. Flowers dry beautifully for winter arrangements; cut stems and hang upside down in a warm, airy place for 1–2 weeks. Dried flowers will last for months if stored in a cool, dry location away from direct sunlight.
