Convallaria majalis /ˌkɒnvəˈlɛəriə məˈdʒeɪlɨs/, 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.It is possibly the only species in the genus Convallaria (or one of two or three, if C. keiskei and C. transcaucasica are recognised as separate species). In the APG III system, the genus is placed in the family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae). It was formerly placed in its own family Convallariaceae, or earlier, like many lilioid monocots, in the lily family Liliaceae.A limited native population occurs in Eastern USA (Convallaria majalis var. montana). There is, however, some debate as to the native status of the American variety.
