Nasturtium
Tropaeolum majus
📖 About this plant
A cheerful, versatile vine with round, lily-pad-like leaves and vivid trumpet-shaped flowers in warm shades of orange, red, and yellow. Both flowers and leaves are edible with a delightful peppery, watercress-like flavor, making them popular in salads and garnishes. Easy to grow from seed, it thrives in poor soil where other plants struggle, making it perfect for beginner gardeners.
