Malanga is one of the staple foods on my homestead. This particular one is the largest Malanga I have ever harvested. It has grown for one year from a golf ball size to 4 lbs or 1.8 kilograms.
They are very easy to grow. I can simply plant them, walk away, and come back to harvest them one year later. After one year, 10-30 smaller corms will grow from the original one. Each corm can become another plant if I don't eat them all. :)
They like to grow in wet soil and can thrive in shady places. Therefore, they are ideal food plant for the herbaceous layer in a shady and low-lying area in a food forest.
