Ease of Cultivation and uses: Nasturtium ‘Alaska’ is a vibrant and unique variety known for its attractive foliage and bright, colorful flowers. This plant is relatively easy to grow, making it a favorite among both beginner and experienced gardeners. With its ability to thrive in various soil types, ‘Alaska’ is an excellent choice for adding a splash of color to gardens, containers, and hanging baskets. The flowers and leaves are edible, offering a peppery flavor that enhances salads, garnishes, and other dishes.

Direct Sowing: For direct sowing, plant the seeds outdoors after the last frost date when soil temperatures are around 60°F. Sow the seeds 1/2 inch deep and space them about 10–12 inches apart to allow for ample growth. Germination usually occurs within 7–14 days. Keep the soil consistently moist until the seedlings are established, but avoid overwatering. Nasturtiums will flourish in full sun to partial shade, and the plants can spread quickly, so consider providing some support for the vines.

Early Sowing for Seedlings: To start early, sow ‘Alaska’ seeds indoors 4–6 weeks before the last expected frost. Use seed trays filled with a quality potting mix and plant the seeds 1/2 inch deep. Maintain a warm temperature of around 70°F to encourage germination. Once the seedlings have developed their first true leaves and the danger of frost has passed, transplant them into the garden, spacing them 10–12 inches apart. Water thoroughly after planting to promote strong root development.

Harvesting: To identify when to harvest Nasturtium, look for fully developed flowers and leaves. The best time to harvest is early in the morning when the plants are hydrated. Use scissors to snip the flowers and leaves, ensuring that you leave enough foliage for the plant to continue growing. Nasturtium flowers and leaves can be enjoyed fresh in salads or as garnishes, and they can also be preserved by drying or pickling for later use.
