Galls and other leaf oddities have intrigued me lately. On an early evening walk with my mother a few weeks ago, I picked a bright-colored leaf from the lower limb of a nearby oak tree. I wondered out loud about the light green spots on the surface. My brother’s sweet and observant four-year-old grandson, who had just presented me with some tiny yellow, roadside flowers, said, “I’m pretty sure it’s frog footprints.”
Those of us in the grown-up world might think those spots are actually a kind of leaf blister called Taphrina caerulescens. But, for now, we’ll keep that information to ourselves.
For a four-year-old, there’s plenty of time to learn about botany and plant diseases and factual reasons for green spots. Frogs and their footprints are the reality for now.
