Description
The plant grows either in water or on moist ground. The plant has thick, spade-shaped green leaves that may be above or below the water surface. Its blue or purple flowers have six narrow petals. These petals may be ground into a paste that is similar to aloe vera, soothing to wounds and burns. The paste does however have a mild neurotoxicity in large quantities that is negligible in small wound applications.
