EASY TO START OUTDOORS: Sow seeds in spring once all danger of frost is over in full sun (or part shade in hot climates). Nasturtiums need no added fertilizer in most soils. Poke seeds into well-worked soil about 1 inch deep and 3 to 4 inches apart. Press soil firmly over the seeds and keep moist. When seedlings are large enough to handle, thin to 10 inches apart so plants will have ample room to grow.
TO START EARLY INDOORS: Sow 2 seeds each in individual 4-inch pots of well-drained seed starting mix 3 weeks before last expected frost date. Cover 1 inch deep. Provide a strong light source. When seedlings have several sets of leaves and night temperatures are above 50°F (10°C), gradually acclimate to outdoor conditions. Transplant seedlings into the garden 10 inches apart in full sun.
GROWING NOTES: These mounding nasturtiums are reliable and easy to tuck into any well-drained spot. They are a perfect disguise to cover fading bulb foliage in late spring. Their softly draping leaves and wonderfully colored flowers will quickly fill garden beds or containers. In mild winter climates, sow seeds again in early July for late summer blooms. Leaves and flowers are tasty additions to salads and sandwiches.
