While having your fruits dispersed by critters is often part of plants’ reproductive strategy, they rarely benefit from losing leaves to herbivory. So if you were a plant, you’d want to research the cost/benefits for different strategies, and consider investing in a decent anti-herbivory portfolio. You could produce secondary metabolites that taste terrible or are toxic. You could grow a bunch of thorns, spines, or trichomes. Or you could just make yourself look too sketchy for visually discerning herbivores to eat. Leaf variegation occurs variably in Virginia waterleaf plants (Fig. 1: an attractive example), and when it does occur, it’s only seen on early-season leaves. A 2008 study on the anti-herbivory impact of variegation in waterleaf plants found that plain leaves sustained twice the herbivory damage as speckled leaves.* Variegation can mimic the look of unhealthy leaves, and can also camouflage the leaf in dappled light conditions of spring. It’s also just kind of a great look, aesthetically? Virginia waterleaf doesn’t feel the need to sacrifice style OR practicality and YES it did wake up like this. *Campitelli, Stehlik, and Stinchcombe. 2008.
