Growing Instructions

1. Planting Season: Sow seeds from late spring to early summer, allowing young plants sufficient time to develop before winter.
2. Soil Preparation: Prepare a sandy or gravelly growing medium with excellent drainage. Avoid heavy, persistently wet soil.
3. Seed Preparation: Use correctly identified seeds. Routine cold stratification is not generally required, although seed-lot responses may vary.
4. Sowing Method: Sow seeds individually in small containers filled with lightly moistened, well-draining seed-starting medium.
5. Sowing Depth: Cover seeds lightly with a thin layer of fine growing medium. Avoid deep burial.
6. Plant Spacing: Allow approximately 24–36 inches between plants to accommodate mature leaf rosettes.
7. Sunlight Requirements: Provide full sun in a sheltered location with adequate space for the mature flowering stem.
8. Watering: Keep the seed-starting medium slightly moist during germination. Water established plants as needed while avoiding saturated soil.
9. Germination: Maintain temperatures around 55–61°F with suitable moisture and airflow. Germination timing varies among seed lots.
10. Transplanting: Move young seedlings carefully into individual containers. Plant into their final location before roots become extensively established.
11. Fertilizing: Use moderately fertile soil and apply additional fertilizer only when growing conditions indicate a need.
12. Plant Care: Protect developing rosettes from freezing temperatures and prolonged winter wetness. Avoid unnecessary root disturbance.
13. Flowering and Pollination: Mature plants produce a tall spike of densely arranged reddish-pink flowers, generally during late spring or early summer. Visiting insects may pollinate the blossoms.
14. Maturity and Seed Harvesting: Allow the flowering spike to mature and dry after blooming. Collect developed seeds before natural dispersal and store them in labeled containers.
