    Like many other plants with sticky leaf surfaces, sticky geranium is protocarnivorous; it is able to dissolve insects that become trapped on its leaf surface and absorb the nitrogen derived from this protein. This characteristic helps G. viscosissimum survive and thrive in nutrient-poor environments.
