This plant is a N. American species of potatoes and it can probably be grown in much the same way as potatoes are grown. This species can survive frosts down to 27 °F (-3 °C). It is advised to list the tubers and store them dry over winter then replant them in the spring. That said my plants survived quite happily left in the pots.
