Tropaeolum majus is an annual plant from the Tropaeolaceae family of plants. It is native to Central and South America. It is also known as Nasturtium (meaning nose-twister), Nasturtium, Common Nasturtium, Mexican Cress, Peruvian Cress, Indian Cress, or Garden Nasturtium. It is a fast and easy-grower and it rewards you with flowers for a long season, practically from spring to winter.
Tropaeolum majus can be a climber, ground cover, or a small bush. It is usually about 12in or 30cm high but if it is trained to climb it can climb as tall as 8ft or 2.4m. Tropaeolum majus has funnel-shaped flowers in bright yellow and orange colors with five petals and the leaves are peltate, round and almost parasol-like. Tropaeolum majus is aromatic.
Plant Tropaeolum majus in the sun in average soil but well-drained, note that very rich soil will increase foliage and reduce flowers. They tolerate shade but the sun is better unless you are in a very hot climate where a bit of shade is appreciated as they do like a cool summer. They are generally disease-free and pest-free, they are also deer-resistant but do watch out for blackfly or caterpillars, slugs, and flea beetles. You can deadhead Tropaeolum majus to increase flowering. They attract butterflies.
Propagate by seeds, the seeds are larger and black, and are produced in a 2cm or 1/2in fruits after flowers are done. They do self-seed. All the above ground parts of the Tropaeolum majus is edible. It tastes slightly peppery and is used in salads both the leaves and the flowers. It has the same vitamin C nutritional level as parsley does. And the unripe seed pods are sometimes put in vinegar and used instead of capers. You can plant the seeds early for a longer season or even as late as May or June will still give you a nice flowering season.
