About Nasturtium
Nasturtium is one of the most cheerful and rewarding plants you can grow. A vigorous annual with sprawling stems that can climb or cascade up to 2 metres, it fills the garden with bright orange, red, and yellow blooms. Both decorative and edible, its round leaves, colourful flowers, and green seed pods offer a fresh peppery flavour similar to watercress. Whether planted in the ground, containers, or hanging baskets, nasturtiums bring bold colour, flavour, and pollinators into your space all summer long.

Where Can You Grow Nasturtium?
Nasturtiums thrive in Zones 3-9 and grow best in full sun with well-drained soil. Avoid overly rich soil, which will encourage foliage at the expense of blooms. They are perfect for planters, vertical supports, along borders, or spilling over garden walls.

History and Historical Uses
Native to South and Central America, nasturtium was introduced to Europe in the 16th century, quickly becoming a garden favourite for its vibrant appearance and culinary potential. All parts of the plant have been traditionally used in salads, herbal vinegars, and for garnishing dishes. The leaves and flowers are rich in vitamin C and the unripe seed pods are often pickled as a caper substitute.
