Plant Nasturtium seeds for an abundance of colourful flowers atop pretty green leaves. The whole plant is edible; the stems, leaves, flowers, and seed pods. The flowers add an exotic flourish to summer dishes, the leaves and stems pack a peppery punch, and the seed pods can be used as a caper substitute. Nasturtiums are easy to grow and look striking tumbling from containers or adding bright colour to the garden bed.

Blooms time: Early summer to frost.
