Mashua Tubers

Tropaeolum tuberosum

Mashua (pronounced Mah-shwuh) is an Andean tuber. A relative of the garden nasturtium, Mashua is one of the highest-yielding, and easiest-to-grow of the Andean tubers, and most resistant to cold. It also repels many insects, nematodes, and other pathogens, thus making it a valuable plant to intercrop with other species. The tubers about the size of small potatoes have shapes ranging from conical to carrot-like. Mashua is high yielding, even under conditions of almost no management. Even the leaves are edible!
