Multiflora Rose, Rosa multiflora, is present no matter where I look around the lake. Native to Japan, Korea, and Eastern China, this species was introduced from Japan in 1866 as rootstock for ornamental roses. Although considered a pest in some states, it's use as a resilient ground cover for wildlife and as an erosion preventative make it mostly considered beneficial. The walls of flowers in select locations around the lake provide a wonderful scent and beauty.
The flowers range from pure white into pastel pinks. They don't really show their true beauty, it seems, until one gets up close to take in the delicate and showy stamens.
