Description
Tall Climbing Mixed Nasturtium Seeds 5800.
Vigorous 2-Metre Vines Bursting with Colorful Edible Blooms for Trellises, Fences, and Ground Cover.
Tall Climbing Mixed Nasturtium (Tropaeolum majus) is a vigorous open-pollinated annual celebrated for its long, rambling vines that easily reach 2 m in height or length. Producing a brilliant floral display in a rich palette of red, orange, and warm yellow, this climbing variety features lush, shield-shaped green leaves and edible semi-double blossoms. Perfect for twining up fences, trellises, and arbours (with a little initial guidance to attach to supports), or left to scramble across sunny garden beds as a dense, weed-suppressing ground cover. Both the colorful flowers and tender leaves offer a signature crisp, peppery taste that elevates summer salads and floral garnishes.

What you need to know to Plant & Grow
Nasturtiums possess delicate root systems that dislike transplanting, so direct outdoor sowing in late spring yields the best results.
-
Direct Sowing (Recommended): Sow large seeds directly outdoors in late May once soil has warmed and spring frost risks have passed. Plant seeds 2.5 cm deep and 5 cm apart in well-draining soil. (Note: Avoid high-nitrogen fertilizers, which encourage heavy leaf growth at the expense of flower production).
-
Germination & Thinning: Seeds typically emerge within 12 days. Thin young seedlings to 20 cm apart to allow vines room to climb and trail.
-
Support & Site Conditions: Full sun is preferred for maximum bloom output, though partial shade is beneficial in hotter mid-summer regions. Provide a trellis, fence, or netting and gently guide young vines onto the support as they grow.
-
Care & Maintenance: Remove spent flowers regularly to extend the blooming period straight through to autumn frost.
