Swiss cheese plant, after reaching maturity, has broad leaves that can measure nearly three feet across. They are perforated with holes and deeply split along the edges. The thick stems bear aerial roots that can be cut off if desired. The plant is a climber and will require some support.
In good conditions, callalike flowers are followed by edible fruit. Although tolerant of low light, plants without at least some sun per day will lose their holes and revert to their juvenile heart-shaped form.
