Snakes-beard (Ophiopogon) - Herbaceous perennials, about 1 1/2 feet high, the flowers, usually small, lilac, appearing late in summer and in autumn in spikes, 2 to 5 inches long, rising from grassy tufts of evergreen foliage. They thrive in borders or margins of shrubberies in sandy loam, but are scarcely ornamental. O. japonicus, Jaburan, spicatus, Muscari, and longifolius are the best known, and usually in botanical collections. In Italy they are used to form green turf in lieu of grass, which perishes from the heat. Division. Japan and India.
