Coleus esculentus

About

Coleus esculentus, synonym Plectranthus esculentus, also known as the kaffir potato or Livingstone potato, is a species of plant in the mint family Lamiaceae. It is indigenous to Africa, where it is grown for its edible tubers. It is more difficult to cultivate than Coleus rotundifolius, but able to give greater yields. Although the crop is similar to a potato, it is from the mint family, but it is still quite nutritious and useful. This crop can benefit many subsistence farmers since it is native, easy to grow, enjoying growing popularity in the market, and quite nutritious.
