Spring/Summer/Fall bloom
Frost tender
In spring, when danger of frost is past, sow seeds in a sunny spot (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 5 inches apart. Press soil firmly over the seeds and keep moist. When seedlings are large enough to handle, thin to 10 inches apart as mounding plants need 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 weather is evenly in the 50°F (10°C) range, 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 sunny flowers will quickly fill garden beds or containers. Hummingbirds come readily to drink the blossom’s nectar. Leaves and flowers are tasty additions to salads and sandwiches.
