Oca

Friends,
I was surprised that it wasn't pictured in the PBS wiki. I
guess the plants are less than ornamental.
From Google images, there seem to be a range of tuber colors
and shapes. Are these really all the same species?

Apparently a New Zealand cv called 'Red' or "Pink" Oca has
close to round tubers and a waxy shine to them. Seems to be a
dominant edible cv. Is this true.

Other forms are rounded ovals, pointed 'carrot' shapes and in
colors including yellow, orange and tan.

I wonder how much variety there is in the plants from these
different tubers.

Liz, is Oca a year round crop or more seasonal?

Thanks all. Jim W.
