Germination & Seedling
2-3 weeksSeeds germinate in 7-14 days at 65-70°F. Seedlings develop first true leaves and establish initial root system.
Keep soil lightly moist but not waterlogged. Provide bright light without direct heat. Thin seedlings to proper spacing once they have 2-3 true leaves.
Vegetative Growth
3-4 weeksPlant develops multiple stems and increasingly dense foliage. Leaves are opposite, lance-shaped, and slightly toothed. No flowers yet.
Water moderately and allow soil to dry slightly between waterings. Pinch back growing tips to encourage bushier growth. Feed monthly with balanced fertilizer if soil is poor.
Flowering
8-12 weeksDelicate flowers appear on tall, slender spikes in shades of purple, pink, or white. Flowers bloom progressively from bottom to top of spike. Very attractive to bees and butterflies.
Deadhead spent flowers to encourage continuous blooming. Ensure adequate sunlight for prolific flowering. Continue moderate watering.
Seed Production & Ripening
4-6 weeksIf flowers are allowed to mature, small seeds develop in dry capsules. Seeds turn brown and hard as they ripen.
Allow some flowers to go to seed for self-sowing or seed collection. Seeds can be harvested when capsules turn brown.
Winter Dormancy
3-5 monthsIn cold climates, plant dies back to ground level. In mild climates, may retain some foliage or regrow from basal rosette.
In cold zones, mulch around base after first frost to protect roots. Cut back dead stems in early spring. In mild climates, may not need winter protection.
