A frost-tender shrub, it can be grown as an annual in temperate climates where it can flower and set seed in its first year of growth[200, K]. Plants can also be overwintered in a cold greenhouse if the winter is fairly mild[K]. As the specific name of this plant suggests, the leaves vary widely in shape. The first leaves to be produced are semi-circular in shape, but later leaves are distinctly three-lobed[K]. Plants are self-fertile[K].
