Trailing Nasturtium

(Tropaeolum majus)

Trailing Nasturtium is a vibrant, fast-growing flowering plant known for its bright blooms and round lily-pad–like leaves. Unlike bush varieties, trailing nasturtiums spread and cascade beautifully over garden beds, trellises, and containers. Native to South America, this easy-to-grow plant thrives in poor soils and sunny conditions, making it a favorite for beginner gardeners and educational gardens. In addition to its colorful appearance, the entire plant—flowers, leaves, and seeds—is edible and often used in salads.
