Seed/Germination
7-14 daysTiny seeds require light for germination. Seedlings emerge as delicate, narrow-leaved sprouts.
Sow on soil surface under lights or in bright conditions. Keep soil moist but not waterlogged. Germination occurs in 7-14 days at 65-70°F.
Seedling & Establishment
3-4 weeksYoung plants develop their characteristic narrow, waxy foliage and establish a deep root system.
Thin seedlings to proper spacing. Keep soil evenly moist but not soggy. Transplant when 2-3 true leaves appear. Avoid overwatering.
Vegetative Growth
4-6 weeksPlants grow taller with increasingly robust stems and denser blue-green foliage. Root system deepens.
Allow soil to dry between waterings once established. Apply light fertilizer (low nitrogen preferred). Stake or support if needed in windy locations.
Flowering
6-10 weeks (or longer with deadheading)Tall flower spikes emerge with bright yellow snapdragon-like blooms clustered densely along the stems. Can reach 2-4 feet tall.
Deadhead spent flowers to encourage continued blooming. Reduce watering further; the plant prefers dry conditions during bloom. Minimal fertilizer needed.
Seed Production & Dormancy
4-8 weeks, continuing into winterAfter flowering, seed pods form along the stems. Plant may self-seed prolifically if allowed.
Leave some flowers for seed production if desired. Cut back after flowering or leave for winter interest. Expect volunteer seedlings the following spring.
