About this plant
There are around 20 species of these perennials. They are found growing both in boggy and marshy places at the edge of ponds, and, in a few cases, submerged within it. They are found growing in both tropical and cooler parts of the world. As the popular name 'arrowhead' suggests they have arrow-shaped leaves that are held on sturdy stems and produce small flowers, generally coloured white and poking up beyond the foliage. There are a few popular forms which are valued for their pronounced vertical accent. There are dwarf and variegated forms occasionally available. The forms that live beneath the water also produce white flowers that float on its surface.
