Lily of the Valley (Convallaria majalis)
Lily of the Valley, a favorite ornamental ground cover for shady spots, is a frequent escape from gardens; it may sometimes mark old homesites, as a patch can persist indefinitely. It comes from the Old World, but it is also apparently native (there is some debate) to the Appalachians; if so, however, its native range is well to the south of our area. When we see Lily of the Valley growing in the wild, we may regard it as a guest rather than a resident. These plants were blooming in the middle of May deep in the woods in Bird Park, Mount Lebanon.
Gray describes the genus and the species:
CONVALLÀRIA L. LILY OF THE VALLEY. Perianth bell-shaped, white, with 6 short recurved lobes. Stamens 6, included, inserted on the base of the perianth; anthers introrse. Ovary 3-celled, tapering into a stout style; stigma triangular. Ovules 4-6 in each cell. Berry few-seeded, red. — Perennial herb, glabrous, stemless, with slender running root- stocks, 2 or 3 oblong leaves, and an angled scape bearing a one-sided raceme of sweet-scented nodding flowers. (From Lilium convallium, the popular name.)
С majàlis L. — High mountains, Va. to S. С. — Apparently identical with the European Lily of the Valley of the gardens which occurs as an occasional escape from cultivation elsewhere within our limits.
