Description

(Tropaeolum minus). Stunning round-leafed nasturtium foliage is brightly variegated. The velvety, deep maroon blooms come as a bonus. A bit somber and very dramatic! You will love this antioxidant-rich plant in salads, soups, and amazing pesto!

Growing Tips: Alaska Red Shades is a stunning heirloom nasturtium that is quite low-maintenance. It grows well in poor to average, well-draining soil and performs best in full sun. Avoid overly fertile soil, as it can encourage leafy growth at the expense of blooms. Regular watering during dry periods will help keep the plants healthy and flowering.

When to Grow

Plant outdoors only after the last frost date in spring, as nasturtiums are frost-sensitive. Check your local area's frost dates to determine the ideal planting time. Seeds can also be started indoors 4 weeks before the last frost using biodegradable pots to minimize root disturbance. In warmer climates (zones 9-11), this variety can be grown almost year-round or as a winter annual. Not sure when your last frost date is? Our blog post 'Our Experts Answer Questions, Share Resources' has all the information you need to find out.

How to Sow and Plant

Nasturtiums are best direct-sown into the garden, as they do not transplant well. Soak the seeds in warm water overnight prior to planting to soften the seed coat and improve germination. Sow seeds 1/2-1 inch deep and space them 8-12 inches apart. Seedlings typically emerge in 7-14 days. If starting indoors, use biodegradable pots to avoid disturbing the roots when transplanting.

How to Grow

Alaska Red Shades nasturtium grows best in full sun, requiring 6-8 hours of sunlight daily for optimal flowering. Water deeply once a week, increasing frequency during hot or dry conditions, but avoid waterlogging the soil. Fertilizers are unnecessary, as rich soil can reduce flower production. Bush-type varieties like this one are ideal as ground covers, while their compact nature also makes them great for pots. Deadhead spent flowers regularly to encourage continuous blooming throughout the growing season.

How to Save Seeds

  • Nasturtiums will often reseed, but to save seeds, allow the flowers to mature and let the petals fall to the ground.
  • Collect the seeds from the plant before they fall.
  • When the seeds are dry, label and store them in a cool, dark, dry place over the winter.
