I want to grow them and planted the Nutty selection from Oikos Tree Crops in October. I think they would be more popular if the tubers were more widely available. Did you grow the native strain?

I have several different kind of apios.
Some Asian country plant widely.
But most country not popular apios and yacon.
Both yacon and apios should be eaten after one month from harvest.
Taste is better than sweet yam.
