Arrowheads (Sagittaria spp.) are a diverse group of plants. Some have above-water arrowhead-shaped or lance-shaped leaves; others grow underwater or have floating leaves. Underwater leaves, particularly of young plants, are narrow and stalkless and usually grow in clumps. Arrowheads have tuber-like roots and can be found along shallow edges of ponds, lakes, and streams and in swamps and marshes throughout Mississippi. Flowers are white and usually in whorls of 3, but there may be as many as 12 flowers in a whorl.
Arrowheads seldom cause any problem, although in a few cases they become serious pests and require treatment.
