Mashua Facts

Mashua is a member of the nasturtium family and is an herbaceous erect or prostrate climbing annual or perennial plant growing 0.5–2 m high, with slender, cylindrical, aerial, green or reddish-green stems that can twine or climb over other plants by tactile petioles. Tubers are produced on axillary stolons that extend to form terminal, elongate, conical or ellipsoid tubers 5–15 cm long and 3–6 cm wide at the distal end, with waxy surface, which are slightly roughened from enlarge scale leaves, generally deeply furrowed, each furrow containing a bud (‘eye) from which it produces aerial stem and adventitious roots. This unique and distinctive vegetable is found used by many people around the world.
