Convallaria majalis, commonly known as the Lily of the Valley, is a sweetly scented [and highly poisonous] woodland flowering plant that is native throughout the cool temperate Northern Hemisphere in Asia, Europe and in the southern Appalachian Mountains in the United States. In the APG III system, the genus is placed in the family Asparagaceae, subfamily Nolinoideae [formerly the family Ruscaceae].
Convallaria majalis is a herbaceous perennial plant that forms extensive colonies by spreading underground stems called rhizomes. The stems grow to 15–30 cm tall, with one or two leaves 10–25 cm long, flowering stems have two leaves and a raceme of 5–15 flowers on the stem apex. The flowers are white tepals [rarely pink], bell-shaped, 5–10 mm diameter, and sweetly scented.
Convallaria majalis is a popular garden plant, grown for its scented flowers and for its ground-covering abilities in shady locations.
