Description
Whirlybird Nasturtium Seeds 5805.
Upward-Facing, Spur-Less Semi-Double Blooms Resting Proudly Above Compact Foliage.
Whirlybird Nasturtium (Tropaeolum majus) is a unique open-pollinated selection celebrated for its distinct spur-less blossoms that sit flat and fully open-faced right atop the foliage, rather than hiding beneath the leaves. Growing to a tidy, compact height of 30 cm, this non-trailing, bushy annual produces a vibrant mix of semi-double flowers in rich shades of red, tangerine, golden-yellow, and salmon-pink from early summer straight through until autumn frost. Perfect for hanging baskets, rock gardens, patio containers, and sunny flower beds, both the colorful blooms and shield-shaped leaves are completely edible, adding a crisp, peppery flavor and gourmet flair to summer salads.

What you need to know to Plant & Grow
Nasturtiums possess sensitive root systems that resent transplanting, making direct outdoor sowing in late spring the most reliable method for success.
-
Direct Sowing (Recommended): Sow large seeds directly into well-draining outdoor soil in late May once spring frost risks have passed and soil has warmed. Plant seeds 2.5 cm deep and 5 cm apart. (Note: Avoid high-nitrogen fertilizers, which encourage dense foliage at the expense of flower production).
-
Germination & Thinning: Seeds typically emerge within 12 days. Thin seedlings to 20 cm apart once established to allow room for neat, bushy development.
-
Sunlight & Climate Care: Full sun produces the most profuse blooming display, though light partial shade is beneficial during peak summer heat.
-
Care & Maintenance: Remove spent flowers regularly to extend the blooming period through autumn.
