Grows well just like a mint but this one is slower and not invasive. It is a good ground cover and produces small edible tubers that look funny, just like larvae. The taste is crispy and nothing special. Grows well in shade or sun, likes some humidity.

Loves a well drained, fertile soil in sun. Give this one some space to spread and it will pay you back in tubers.

Cultivated for it's small edible tubers that can be cooked much like Jerusalem Artichoke.
