Arrow arum – Peltandra virginica
Arrow arum occurs throughout Florida. It is a native species. Arrow arum is found in swamps and marshes, and along muddy shorelines of streams and lakes. It grows in areas of high light and darkest shade. Arrow arum flowers from February to September. Arrow arum leaves are arrowhead-shaped, with an obviously rounded leaf base. Leaves typically are 10 to 12 inches long, and half as wide. They may be twice as big. The leaf underside is whitish, with three prominent veins. Its leaves are clustered on long succulent stalks that can be 3 feet long. Arrow arum flowers are small and light yellow, on a finger-like spike. The flower spike is surrounded by a bract (or spade). In this species of Peltandra, the bract is yellowish-green, and spreading only slightly. Arrow arum leaves may be confused with those of either common arrowhead or wild taro plants. Arrow arum leaves are arrowhead-shaped, with obviously rounded leaf lobes. Common arrowhead leaves are arrowhead-shaped, with pointed leaf lobes. Wild taro leaves are umbrella-like. The stems attach more or less in the middle of the leaf. Arrow arum leaves attach at the base margin of the leaf.
