Seedling
3-4 weeksTiny seedlings with 2-4 true leaves emerge. Growth is initially slow.
Keep soil lightly moist but not wet. Provide bright light and good air circulation to prevent damping off. Thin seedlings to prevent crowding.
Vegetative
6-8 weeksPlant develops a basal rosette of narrow, lance-shaped green leaves. Gradual height increase occurs.
Water moderately. Ensure excellent drainage. No fertilizer needed; too much nitrogen encourages leaf growth over flowers. Harden off transplants before planting outdoors.
Flowering
4-8 weeksTall flower spikes emerge with tubular scarlet-red flowers opening progressively from bottom to top.
Deadhead spent flowers to encourage continued blooming. Provide staking if plants become tall and leggy. Water at soil level to keep foliage dry.
Seed Production
3-4 weeksFlowers fade and are replaced by seed pods (capsules) that dry on the plant.
Allow some flowers to mature to seed for self-sowing or seed collection. Collect seed capsules before they split and disperse naturally.
Dormancy
3-4 monthsPlant enters winter rest period with semi-evergreen foliage persisting in mild climates.
Reduce watering significantly. Provide winter protection in cold zones (zones 3-5) with mulch around the base. Cut back dead flower stalks after frost.
