	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.
