Mashua – Ancient Vegetable Harvest and Transplanting – Video

Mashua (Tropaeolum tuberosum) is a vegetable that has been used by humans for 8000 years and has been in cultivation for about 1400 years in Peru and Bolivia at over 3000 meters above sea level. It has been grown along side of the famous potato, as well as yacon and oca.

It is a tuberous nasturtium very well suited to our cold temperate maritime climate in Ireland. In spring, when it’s still cold and not much else is growing, mashua takes off to an early start and it almost takes over the place with it’s climbing shoots. In fall it flowers and retracts back into fresh tuberous stored underground for the winter well protected from the frost. No artificial storage and replanting required, same as the potato and the oca when using woodchip mulch. In our gardens they have been coming back year after year more vigorous.

The whole plant is edible i.e. leafs, flowers in salads and the tubers are best roasted but can be eaten raw.

  1. Ooh sounds interesting, thanks for sharing! Where did you get the tuber from please ? Thanks Davey

    1. Hi, usually all tubers are only sold bare root in the winter time when they’re dormant, it’s easier to post them. I don’t know of any place that would sell them as plants during the summer. It’s not really worth while posting mashua plants. If you want i could let you know once the mashua plants have receded in october. I’ll email you then. Thanks

  2. What light conditions does this do best in? Full sun, partial shade or full shade? Thank you.

    1. We always set up different micro climates in our gardens for longer harvest seasons and resilience. Mashua did well both in semi shade and full sun. Bare in mind that it’s a climber so it’s at searching for extra sun light.
