Lily-of-the-valley Overview
Lily of the valley (Convallaria majalis) is a small, herbaceous plant that is native to Europe and Asia and is known for its bell-shaped flowers and its red berries, which grow in the summer and fall. It is a popular ornamental plant.
Lily of the valley has been traditionally used for cardiovascular conditions but is not recommended due to safety concerns.
