Spring/summer/fall bloom
Frost tender
Sow seeds in spring once all danger of frost is over in full sun or part shade in hot climates. Nasturtiums will grow and flower readily with 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 10-12 inches apart so plants will have ample room to grow.
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 pinch out the weaker seedling, leaving 1 per pot. When night temps are above 50°F (10°C) gradually acclimate to outdoor conditions. Transplant seedlings into the garden 10 inches apart in full sun.
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 and gladden garden beds or containers. Both leaves and flowers are tasty, spicy-sweet additions to salads and sandwiches.
