Moonlight Nasturtium is a vigorous climbing annual that transforms from seed to full bloom in 70 to 84 days, reaching 4 to 6 feet tall when given support. This heirloom variety thrives in full sun with moderate water, producing nonstop flowers from early summer through the first frost. Its deer-resistant blooms attract pollinators throughout the season, making it both beautiful and ecologically generous in the garden.

Moonlight Nasturtiums are remarkably reliable growers that demand almost no fertilizer yet reward you with continuous blooms. Plant them to climb a trellis or let them tumble along the ground, and they'll adapt cheerfully to either role. The real appeal lies in their unfussiness: they thrive in poor soil, resist deer, and bloom prolifically without the nitrogen-rich feeding that would actually work against you.
Moonlight Nasturtiums are grown primarily as ornamental flowers that brighten gardens and vertical spaces from midsummer through fall. Their trailing or climbing growth habit suits them to containers, window boxes, trellises, and garden beds where they provide continuous color and pollinator activity.

Sow 2 seeds each in individual 4-inch pots of well-drained seed starting mix 2 to 4 weeks before your last expected frost date, covering seeds 1/2 to 1 inch deep. Maintain soil temperature around 65°F and provide strong light. Germination occurs within 7 to 14 days. Once seedlings have several sets of leaves, pinch out the weaker one, leaving 1 plant per pot. After outdoor temperatures stay evenly above 50°F (10°C), gradually acclimate seedlings to outdoor conditions over several days before transplanting.
Transplant seedlings into the garden when outdoor temperatures remain consistently above 50°F. Space plants 10 to 12 inches apart in full sun and well-drained soil.
Direct sow seeds into well-drained soil after your last frost date, when soil temperatures have warmed to at least 50°F. Cover seeds 1/2 to 1 inch deep and keep soil moist until germination occurs in 7 to 14 days.
Pinch seedlings early to encourage bushier growth, removing the weaker seedling in each pot during the indoor stage. No additional pruning is required once plants are established in the garden.
