Description
Arrowhead is a perennial aquatic herb that grows in static or slow-moving shallow fresh water, such as drains and pond margins. It has a thick rootstock without creeping stems (unlike other sagittarias). Its large glossy arrow-shaped leaves are carried on stalks of up to 1 m above the water. Its flowers are composed of three large white petals with a purple blotch at the base.
Impact
