Arrow arum is an emersed plant that is commonly found in swamps and marshes throughout the state and blooms from winter to spring (Wunderlin, 2003). It grows in areas of highest light and darkest shade.
Arrow arum leaves are arrowhead-shaped. They typically are 10 to 12 inches long and half as wide. The leaf underside is whitish with three prominent veins. Its leaves are clustered on long succulent stalks, that can be three feet long. Arrow arum flowers are small and light yellow, on a fingerlike spike. The flower spike is surrounded by a bract, or spathe, that is usually yellowish green. In the spoon flower, Peltandra sagittifolia, the bract is more open and showy white.
