This leaf is from a mystery perennial in my garden. I planted it last summer and it never bloomed. It grew quite vigorously this spring and is now a couple of feet tall and full of buds. I have no idea what it is. I'm intrigued, though, and looking forward to solving the mystery in the coming days.
I painted the leaf with watercolor, turned it over onto watercolor paper and then weighted it with books for an hour or so. That left a faint leaf design, which I then enhanced with ink and more watercolor.
