Peace Lily is a classic ornamental plant and a long-time favorite of many plant hobbyists and collectors. While its flowers remind you of calla lilies, this famed air cleaning plant is not a true lily since it’s actually a part of the Arum family. The leaves are attractive as they are - glossy, dark green, and lance-shaped that arch out from the plant’s base. Yet, the white flowers are the main attraction. They form a club-like cluster, surrounded by an elegant white bract.
