Overview

Anu, scientifically known as Tropaeolum tuberosum, is a perennial plant native to the northwest regions of Argentina, Bolivia, Colombia, Ecuador, and Peru. This member of the Tropaeolaceae family thrives in full sun with moist, light (sandy) to medium soil, making it suitable for gardens with well-draining conditions. Anu is valued for its edible tubers, which can be harvested and enjoyed as a food source. The plant grows up to 2 meters tall, creating an impressive presence in the garden. Its tubers are often eaten raw or cooked, providing a nutritious addition to meals. Drying the tubers is another common method of preparation, allowing for storage and use throughout the year. Anu is hardy in zones 7-10, so it needs protection in colder climates. For propagation, tubers can be used, ensuring consistent moisture in the soil while avoiding waterlogged conditions. While not medicinal, Anu's edible tubers offer a unique and nutritious addition to the diet.
