Seed Germination
1-2 weeksTiny seedlings emerge with cotyledons (seed leaves); very delicate at this stage
Keep soil consistently moist but not waterlogged. Provide bright light. Germination takes 7-14 days at 65-70°F.
Seedling & Establishment
2-4 weeksFirst true leaves appear; small rosettes develop close to soil surface
Thin seedlings to appropriate spacing. Keep soil lightly moist. Begin hardening off if grown indoors.
Vegetative Growth
4-8 weeksPlant develops bushy foliage with multiple stems and leaves; no flowers yet
Water regularly, pinch back tips to encourage bushiness. Foliage is harvestable at this stage for culinary use. Apply balanced fertilizer monthly.
Flowering
6-10 weeksStems elongate and produce clusters of small white or pale pink flowers with characteristic inflated sepals
Continue regular watering. Deadhead spent flowers to encourage more blooms. Flowers are delicate and attract bees and butterflies.
Seed Production & Maturity
4-6 weeksFlowers fade and seed capsules develop within the bladder-like sepals; seeds mature and dry
Allow some flowers to remain for seed production if desired. Collect seed pods when they turn brown and papery. Plant is fully perennial and will overwinter in cold climates.
