Giant Arrowhead (Sagittaria latifolia) has distinctive leaves shaped as the name indicates and stands one to three feet above the water. Flowers are produced freely in a series of spikes.
The Giant Arrowhead is a perennial monocot with rhizomes. The emerging leaves start growing underwater. As they mature, the arrowhead forms pointing to the sky. The leaves can grow to 11" L x 9" W depending on the growing environment. It almost always occur in wetlands (Considered OBL, Obligate Wetland).
The approximately 1" cream to white colored petals are in whorls with most subspecies having burgundy colored spots at their bases. These attractive flowers can be found from June to September. Giant Arrowhead is insect pollinated.
The Giant Arrowhead is mostly aquatic yet can be found at your pond edges in shallow, ephemeral water, sometimes occurring in tidal mud flats. This plant can be found across much of North and South America. However, the distribution across the United States is somewhat disjoint, known to occur in some New England and Middle Atlantic States, across the southeastern states, Michigan, and in California.
