My girlfriend asked me to create a painting of a leaf she found, so I painted it in watercolor and then used ink and colored pencil for final details. It’s a Chinese tallow tree leaf. In our neck of the woods, there has been a decades-long fight against these trees because they’re an invasive species with toxins in their leaves that make the soil uninhabitable for native species. They naturally create monospecific forests if left unchecked. The internet tells me that they were introduced to the Gulf Coast of the U.S. for soap-making in the early 1900s.
