Lily of the Valley

Convallaria majalis, sometimes written lily-of-the-valley, is a woodland flowering plant with sweetly scented, pendent, bell-shaped white flowers borne in sprays in spring. It is native throughout the cool temperate Northern Hemisphere in Asia and Europe. Convallaria majalis var. montana, also known as the American lily of the valley, is native to North America.

Due to the concentration of cardiac glycosides (cardenolides), it is highly poisonous if consumed by humans or other animals.
