Growing Non-GMO Alaska Nasturtium Flower Seeds

Alaska Nasturtium is easy to grow from seed and recommended for direct sowing outdoors when the soil temperature is at least 50 F. Start Alaska nasturtium seeds indoors 6-8 weeks prior to the final frost. Nasturtium seeds will germinate in 2-3 weeks. After germination, move under a fluorescent grow light for 16 hours of light per day until two sets of true leaves have developed. Transplant seedlings to indoor containers, or harden off if transplanting to a shaded spot outside. If starting indoors, be sure to harden off before planting outdoors. For direct sowing, plant 2-3 Alaska Nasturtium seeds per hole. The optimal soil temperature is 65°F for germination and plant growth. Plant again in early July for continuous blooms throughout mild winters.

Mulch around the base of the plants to suppress weeds and decrease watering needs. Deadheading spent blooms or removing prime blossoms for consumption will increase flower production throughout the season. Nasturtiums are one of the first spring plants to bloom with vibrant colors and will be one of the last to fade in the fall with minimal effort on your part! Alaska also performs remarkably well in containers. Group 3-5 plants in a 10-inch deep pot for a full, bushy look. Provide mulch and increase the watering schedule when growing in containers. Nasturtium will self-sow in mild winters. Although Alaska nasturtium is tolerant to drought and poor soil, plants will show signs of wilt and decline by mid-summer once daytime heat becomes too extreme. Unlike other types of nasturtium, Alaska is a variegated variety and can thrive in full or part sun.

Harvesting Alaska Nasturtium

Many cooks and gardeners use the leaves and flowers in salads, sushi, and other dishes. They are similar to water-cress in flavor and texture. The flavor is described as slightly peppery. With the exception of its roots, the nasturtium plant is entirely edible, including its leaves, pods, seeds, buds, and especially the flowers. It is often used in salads and stir-fries.

About Alaska Nasturtium Garden Seeds

Tropaeolum majus is native to the warm subtropics of the 10,000-ft high Andes mountains in Bolivia and Colombia. Nasturtium receives its common name from an oil it produces similar to watercress (Nasturtium officinale).

Tropaeolum majus, or Nasturtium, can also be known as Indian cress, Mexican cress, and Peruvian cress.

Nasturtiums are cultivated as perennials in zones 9-11. Simply allow them to persist. Prune back each year to keep them under control. They will self-seed and send up new shoots each spring if not contained.
