I visited my friend and high school art teacher this past weekend. She lives in Stony Brook, LI. Many who came later to this enclave cut down or topped up their oaks to force a lawn. But in her neck of the woods, the canopy of oaks and understory of mountain laurel and introduced rhododendrons reign predominant. Her garden is a place of dappled light and deep greens. She has many hostas, ferns, and snakeroot. I introduced her to snakeroot's cousin, the purple perennial ageratum, two years ago to her delight. In recent years, but with this year standing out, her garden has become quite the home to moss.
