Seedling
4-6 weeksTiny rosette of narrow green leaves emerges slowly. Very slow to establish in first weeks.
Keep soil consistently moist but not waterlogged. Provide bright, indirect light. Patience is key—germination is slow and erratic.
Establishment
6-10 weeksCompact rosette develops with slightly reddish tones appearing at leaf bases and edges. Plant remains low to ground.
Gradually acclimate to full sun. Maintain even moisture. Avoid fertilizer; lean soil produces better color.
Vegetative Growth
Throughout growing seasonRed-purple foliage deepens and expands. Leaves become increasingly burgundy, especially in cool months. Plant mounds outward.
Increase sun exposure for maximum color. Reduce watering frequency. Allow soil to dry between waterings. No fertilizer needed.
Flowering
6-8 weeks (June-July in most zones)Tall spikes of white tubular flowers with red-flushed throats emerge from the red foliage. Multiple flower stems reach 24-36 inches tall.
Deadhead spent flowers to encourage continued bloom. Provide staking in windy locations. Do not fertilize, as this reduces flowering.
Seed Set & Dormancy
Late summer through winterFlowers fade and seed pods develop. Foliage begins to yellow or brown as plant prepares for dormancy. Basal rosettes of new growth may appear.
Allow some seed pods to mature for self-sowing. Cut back after first frost or in early spring. Provide excellent drainage over winter.
