not the same as the original wild variety. What does a wild
potato look like?
Are they available anywhere?

REPLY:

Try the blue potatoes from Peru;  Some seed catalogues have
them.  A friend says they are  still  raised Peru.  I grew
some and they do not get very big,  suggesting they have not
been altered as much as a Burbank potatoe.  (British,  and
Colonial spelling )    If you grew potatoes from seed they
may revert to wild.
