It is definitely a tuber and it definitely grows from the tuber as that is by far the most common way new plants are started. The "Genetics" section of the wikipedia entry for potato is very interesting reading describing a number of different species that are all related to the potato and that various potato species are native from south central Chile all the way up into Texas. Some of these species have even been bred into the commercial potato to introduce different kinds of disease resistance. There are even diploid, triploid, tetraploid, and pentaploid species of potatoes!ki
