Mary's Grass, is also called stiltgrass because of the stilt-like structure at the base of the culm. Some manuals list it as Eulalia viminea. Practically unknown in New Jersey in the early '80s it is now widespread in dense populations. Usually found in moist, shady habitats. It is an extremely invasive grass although not as yet an economically important weed. Field botanists rank it along with purple loosestrife and garlic mustard in its invasive properties.
