Mitchella repens (Partridge berry). This is an often overlooked, wonderful evergreen ground cover for shade/part shade in the garden. It is fairly common in the deciduous forest understory. Unfortunately, I didn’t find any with the red berries still intact (which I hear are edible). This plant is somewhat slow growing and it eventually forms a dense carpet. When in bloom, the little white flowers are structured so that they prevent self-fertilization, thus promoting genetic diversity! And, it is the only plant in its genus in North America.
