This member of the Basellaceae
family was described by Francisco Josť de Caldas in 1809. It is
found in Peru, Colombia, Bolivia, Ecuador and Argentina, grown as a
crop. Grown in sandy or even rich soil with some to lots of water
and some sun. Although it is grown as a annual crop, the plant can
actually grow for several years. It will raise to 30 centimetres,
and the tubers grow up to 10 centimetres, and vary in colour and
shape, depending on soil and subspecies.
I am not sure how well the
tubers will do, if they are raised.
