Mashua (Tropaeolum tuberosum) potted plant, organic


Family:  Nasturtium (Tropaeolaceae)

Perennial in  Zones 8 to 12 where it does best at middle elevations.  As a garden annual, this is a good choice for temperate gardens, where it will mature its tubers by November.

Vining perennial native to Peru and Bolivia, with flattish, palmate leaves and orange, spurred flowers.  Highly desired delicate climbing vine to 8 feet, very very showy on the landscape.  Tender.  The production of the thin-skinned, tuberous roots is stimulated by shortening days, therefore harvested very late in the season.  Tubers are used in soups, being kind to the liver and kidney, also purportedly an anaphrodisiac that gets served up when the lady of the house is feeling exhausted.  When fresh, the mashua are as peppery as a Nasturtium bud, but when cooked they are mild and yummy in taste.  They are particularly nice when roasted along with meats.  The leaves are also edible, as are the buds and flowers.  The tubers make a good pickle.  Plant like a potato.  Trellis.  Benefits from growing in soils of relatively low fertility but good structure.  In hot areas, give shade or partial shade.  Hill up.  Give plenty of water late in the growing season to encourage formation of tubers.  Space plants 3 feet apart.

    Mashua can be grown indoors! It likes to climb and will do well planted next to other larger houseplants in which case it will climb up on them, or lacking living trellis the plant will drape itself on the drapes, ride any convenient rail, or plummet down from a hanging pot like a bungee jumper from a bridge.  Mashua are slow growing and thus long lived indoors, and will rarely flower unless given adequate light, but the leaf form is so interesting that flowers are not really needed in order to fully enjoy the plant.  These are herbaceous perennials and should be cut back in October and overwintered in a cool, somewhat dry location.  The plants may be awakened around April and will vitally reassert themselves, envigorated by their long winter nap.
