The monotypic genus Magallana was characterised by having winged fruit, and the two species of Trophaeastrum lacked spurs. Please login or create an account. Creating a spectacular floral display for months, they contrast nicely against the foliage of dainty, deep green, clover-like leaves. Mashua is easily propagated from tubers. There is also a lesser known, and lovely perennial variety called T. speciosum whose major fault in the plant world is having an unpronounceable name, but is a great climber. It can also be propagated by cuttings.Take six to nine inch sections of stem and set the bottom about two inches deep in damp soil. It has been cultivated since ancient times and depictions of it are found at archaeological sites pre-dating the Incas. [33], This article is about the flowering plants of the genus Tropaeolum, commonly called nasturtiums. The flowers are bisexual and zygomorphic, with five petals, a superior three-carpelled ovary, and a funnel-shaped nectar spur at the back, formed by modification of one of the five sepals. Mashua has photoperiod dependencies for both tuber formation and flowering. They can be put out in the open in the spring, in a sheltered sunny spot. The most serious serious pest of mashua is deer. Discover RHS expert help and advice on growing, feeding, pruning and propagating plants. An unusual, but more serious problem is bears!

Here are some of the best that I have found: According to this study, https://www.ncbi.nlm.nih.gov/pubmed/7057655 , “Experimental animals and controls showed equal capability in impregnating females, although animals fed T. tuberosum showed a 45% drop in their blood levels of testosterone/dihydrotestosterone.” This is the opposite of what you stated above. Cooking breaks down isothiocyanates and I would guess that this moderates or eliminates the anti-metabolic or anti-nutritional factors present in raw mashua. I hope to try to narrow that down in the near future, but it is more important to me to eliminate viruses than to identify them. Incredibly showy, Tropaeolum tricolor (Tricolor Nasturtium) is a summer-dormant, tuberous, perennial climber with a profusion of tricolor flowers from winter to early summer.

The plant has some resistance to light frosts, but a hard frost will kill the foliage completely. These were low titer results on test strips, which might indicate that they are related viruses and not actually those viruses, but I have included them in the table below until that is sorted out. The nasturtiums received their common name because they produce an oil similar to that of watercress (Nasturtium officinale). It dehydrates relatively quickly once dug. These are a fast growing species, they will break the surface and quickly climb up the trellis. In cold climates, there is some urgency to complete the harvest when temperatures of 30° F (-1 C) or below are imminent. Remember that tropaeolum can grow to 2m, so a large wire frame can work well. If you know of a source for any of them, please hook me up! Each flower can produce up to five seeds, but it is rare to see more than two without making hand pollinated crosses.

It does not reduce edibility significantly, but it does affect the appearance of the tubers. Mashua grows best where summer temperatures do not exceed 80 degrees. Tubers will last 6 to 8 weeks at room temperature and moderate humidity before the reduction in quality makes them unappealing for eating. Long sprouts can be cut back, but should not be pulled from the tuber, as this often leads to rotting. Do not pull the full stem free of the tuber.

Mashua leaves can be eaten and taste very similar to mustard greens. If you are growing mashua as an ornamental or as a leaf crop, you may not care about this, but when a tuber harvest is the goal, the only practical method for perennial growing is the “sloppy harvest” method, where you take the large tubers and leave the small ones to grow again. Seed from the winter growing species should be sown in the autumn while the summer growing species are best sown in the spring in well-drained compost and covered with 1 to 2 cm (0.4 to 0.8 in) of grit or sand. This is very similar to the behavior of tetraploid potatoes. I have found only a few viruses infecting mashua in the USA, which is good reason to avoid introducing new, untested varieties.

This would seem to refute the idea that mashua is an anaphrodesiac, but it may be best to limit consumption when trying to conceive since sperm production was slightly reduced. So, mashua consumption may be protective against some kinds of cancer. Most mashua varieties have predominantly white tubers, although yellow, orange, red, and purple tubers are formed by some varieties. Wild mashua’s thickened stolons can barely be categorized as tubers. Pruning Hydrangeas. A few are closer to 12 hours and therefore don’t begin to form tubers until the end of September. Description Description. Genetically, mashua is generally considered to be tetraploid (Gibbs 1978) and displays a fair degree of phenotypic variability in progeny from self pollinated seeds, similar to that seen in tetraploid potatoes (example here). Mashua is a difficult companion because its growth is so rampant. The origin of these botanical varieties is unknown and they don’t appear to be particularly useful. Seven foot (2.1 m) row spacing will leave a comfortable walkway. Mashua grows very well in half barrel or larger containers. Many more viruses have been found infecting mashua where it comes into contact with other crops. 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. Mashua sets many of its tubers at the surface of the soil and these will all be ruined if they are frozen. Please see a doctor about your taste buds.
