Nasturtium Seeds

The easygoing edible flower worth a spot in your garden

Nasturtiums (Tropaeolum majus) are fast, cheerful annuals grown for their vivid trumpet-shaped flowers in red, orange, and gold and their distinctive round, blue-green leaves. Available in both bushy mounding types and long trailing climbers, they spill beautifully from beds, borders, hanging baskets, and walls. Famously undemanding, nasturtiums thrive in lean soil and full sun and bloom generously all summer, making them one of the most beginner-friendly flowers you can grow.

How to grow nasturtiums from seed

Nasturtiums are wonderfully simple from seed. Sow the large seeds about half an inch to an inch deep directly where they will grow, in full sun after the last frost, and space plants eight to twelve inches apart. Seeds sprout in one to two weeks and plants begin flowering in roughly 45 to 55 days. Skip the fertilizer, since rich soil produces lush leaves at the expense of blooms. For the full step-by-step, see our complete guide to growing nasturtiums from seed.

How to use nasturtiums

Nasturtiums are one of the most useful flowers in the garden. The leaves, flowers, and even the young seed pods are edible, with a bright, peppery, watercress-like bite that livens up salads, sandwiches, and butters, and the unripe pods can be pickled as a caper substitute. In the garden the flowers draw bees and hummingbirds, and nasturtiums are a classic companion plant traditionally grown as a trap crop to lure aphids away from vegetables. Their trailing habit also makes them perfect for cascading containers.

Nasturtium and its cheerful annual cousins

If you love nasturtiums, you will enjoy the other easy, edible, and pollinator-friendly annuals they pair with. Try calendula for more edible golden petals, marigold for bold companion-planting color, or zinnia and cosmos for tall, prolific cutting flowers.
