Convallaria majalis commonly known as the lily of the valley or lily-of-the-valley, is possibly the only species in the genus Convallaria in the flowering plant family Ruscaceae (or one of two, or three, if C. keiskei and C. transcaucasica are recognised as separate species). It was formerly placed in the lily family Liliaceae, or in its own family called Convallariaceae. This woodland plant is native throughout the cool temperate Northern Hemisphere in Asia and Europe and a limited native population in Eastern USA, (Convallaria majalis var. montana). There is, however, some debate as to the native status of the American variety.
