The leaves are the point and they are extraordinary: heart shaped, almost translucent, painted in pink, red, white and green in combinations that look printed. It grows from a tuber, and the thing to understand before buying one is that it is not an evergreen houseplant. It comes into leaf in spring, performs all summer, then yellows and dies down completely in autumn and wants to be stored dry and warm until the following spring. People who do not know that throw away a perfectly healthy dormant tuber every October. Give it warmth, humidity, shade from direct sun and steady moisture while it is in leaf, and keep it away from pets.
