Nasturtium Flower Seeds – Edible, Non-GMO

Nasturtium Flower Seeds (Tropaeolum majus)

Brighten your garden — and your plate — with one of nature's most cheerful, easy-to-grow flowers. Diamond Field Blooms Nasturtium seeds produce a cascading abundance of fiery orange, red, and golden-yellow blooms that are as edible as they are beautiful. Whether you're filling a sunny border, trailing over a garden wall, or growing in containers on a balcony, nasturtiums deliver colour, life, and flavour from spring right through to autumn.

Why Grow Nasturtiums?

Nasturtiums are the perfect starter flower — and a rewarding choice for experienced gardeners too. Direct sow into warm soil after the last frost, and you'll see germination within 7–10 days. Plants flower in just 6–8 weeks, with vines reaching 200–300 cm if left to sprawl or climb.

These seeds are:

• Non-GMO and open-pollinated
• Edible — both flowers and leaves have a peppery, watercress-like flavour
• Pollinator-friendly — a magnet for bees and butterflies
• Hardy and drought-tolerant once established

Planting Guide

Sow seeds 2–3 cm deep in full sun, spacing 20–30 cm apart. Nasturtiums prefer poor to moderately fertile soil — rich soil encourages foliage over flowers. Keep soil evenly moist during germination. For vertical growing, provide a trellis or support for the vines.

In the Kitchen

Nasturtium flowers and leaves are entirely edible, making them a favourite among food gardeners. Toss petals into salads, use them as a garnish, or steep them in vinegar for a beautifully coloured, peppery dressing.
