Seedling
10-14 daysTiny seeds germinate into thin, grass-like cotyledons with true leaves following. Seedlings appear delicate with narrow green foliage.
Maintain 65-70°F soil temperature. Provide bright light immediately after germination (avoid dark conditions). Keep soil lightly moist but not waterlogged. Thin to stronger seedlings or prick out into individual containers.
Vegetative Growth
4-6 weeksPlant develops multiple stems and dense gray-green foliage in a compact mound. Leaves are narrow, lance-shaped, and slightly waxy.
Once established, reduce watering frequency. Pinch growing tips when 4-6 inches tall to encourage bushier branching and more flowering stems. Begin light feeding with balanced fertilizer every 2 weeks. Ensure excellent air circulation.
Bud Formation & Flowering
6-8 weeksFlower buds emerge at stem tips, developing into large, double blooms with salmon-colored ruffled petals. Multiple buds appear sequentially on each stem.
Switch to phosphorus-rich fertilizer to encourage blooming. Remove any diseased foliage promptly. Support tall stems with stakes if needed. Remove spent flowers below the first node to encourage branching and continued bloom.
Peak Blooming
4-8 weeks or longer with deadheadingMultiple large salmon-colored double flowers in full bloom simultaneously across the plant. Blooms are fragrant, ruffled, and hold color well.
Harvest flowers in early morning when stems are hydrated. Cut just below a node. Remove faded blooms regularly to extend flowering. Continue moderate watering and feeding. Monitor for pests and disease during high humidity.
Late Season & Decline
Variable; typically 8-12 weeksFlowering slows as temperatures shift. Plant may become woody or leggy. Blooms may appear smaller or less prolific.
In cool climates, plants can be overwintered by cutting back and protecting with mulch. In warm climates, treat as cool-season annual and replace in summer. Collect seeds from best flowers if desired. Otherwise, pull spent plants and add to compost.
