Tropaeolum majus. Annual climber grown for the very popular edible flowers with a bit of a peppery tang, Nasturtium blossoms are often added to salads as a zesty garnish over a citrus vinaigrette. We never have that many flowers as they make great snacks and are eaten quickly! Can reach heights of 3.5m so make sure you plant where it can reach for the sky. Good for bees.
