Oca tubers. A selection to show the range of colours. These are the largest sizes.
Some of the best tubers showing the size and colour range. The best plants produced 0.6 kilo ( 1 lb 6 oz ) each. Some split to create cuttings produced a much higher yield from each seedling.
I estimate 10kg from a seedling from the best, but haven't removed them from the stems yet.Peter Thomson
