Lysimachia ciliata, Fringed Loosestrife
Fringed Loosestrife can be found where woods meets a wetland -it likes dappled shade or part sun and moist soil. Those familiar with the the maroon-leaved sport will know Loosestrife as a rhizomatically spreading plant, some say aggressively so, in a conventional garden setting. Place this species with other wetland edge plants near a wetland, as opposed to a moist spot in the home garden, and the competition will play its role in keeping plants in balance. Drier spots may limit it spread -consider using a ground barrier if the garden is where you would like this worthwhile species.
Blooms: yellow, July into August
