They also appear to play a role in carcinogen detoxiification and/or promotion of apoptosis in pre-cancerous cells (Shapiro 1998). Height and spread: 3m (10') Provide appropriate support, such as a trellis or wires attached to the wall and fences. Mashua varieties in North America sometimes test positive for Potyvirus, which could be Bean Yellow Mosaic Virus, Mashua Virus Y, Tropaeolum Mosaic Virus, Turnip Mosaic Virus, or as yet unidentified mashua viruses. One of the hardiest species is T. polyphyllum from Chile, the perennial roots of which can survive the winter underground at altitudes of 3,300 metres (10,000 ft). ENGLISH : Flame creeper, Flame nasturtium, Ornamental nasturtium, Chilean nasturtium, Scottish flameflower (USA). Mashua is potentially infected by a large number of viruses, in contrast to its reputation as a very disease resistant plant. Significant root formation takes four to six weeks, after which the new plant can be hardened off and moved outside. Some varieties adopt a bush form while others scramble over and through other plants and are useful for planting in awkward spots or for covering fences and trellises.. Several varieties with critical daylengths greater than 13 hours now exist and breeding this trait into new varieties appears to be relatively easily, with roughly 3% of the progeny of crosses between short day and intermediate daylength varieties having similar intermediate photoperiods. * Mashua varieties have tested positive for the genus and these viruses are possible culprits, Mashua frequently demonstrates fasciation, which can be beautiful, but also typically lowers yield. 10 Plants for Year-round Containers . I have had mashua volunteers germinate in the field fairly early in the growing season here, including some from seeds that were buried as deep as four inches. The tubers start growing towards the end of the autumn. It is best if the seed pieces are at least 1/2 ounce (14 g).

Cumin seems to have an almost magical balancing effect against its less appealing flavors. In cold climates, there is some urgency to complete the harvest when temperatures of 30° F (-1 C) or below are imminent.

It is frost-hardy and produces crops of 30 tons per hectare at a height of 3,000 metres (9,800 ft) above sea level. After flowering, the plant dies back. In comparison, after making a cross between two varieties, the self pollinated progeny of that new variety display substantial variation. In dry climates, it is important to give mashua some wind protection, since dry winds will rob it of water faster than it can replace it. it is also commonly known as tuberous nasturtium, añu, cubio, or papa amarga. , Tropaeolum is a genus of dicotyledonous annual or perennial plants, often with somewhat succulent stems and sometimes tuberous roots.
