The name macrorhiza comes from the Greek for 'big root', it is sometimes seen as 'macrorhizus'. It is a vine with ivy like leaves. Young plants do great in a hanging basket. They are relatively easy to grow, and develop rapidly a nice caudex, provided that they get abundant water and fertilizer in summer, and a pot large enough.
