This American type of Arrowhead likes to grow in pond-edges etc. It does take varying water-depths, even temperary dry periods. The plant develops two types of leaves: narrow linear submerged leaves and big pointed-spoon-shaped leaves. The latter energe above water. The plant produces both male and female flowers. The male flowers are reasonably big, white and occur up high on tall stems in whorls, while the female ones are resting lower and look like flattened, green strawberries. Seven subspecies are known, showing only small differencies. For preferably a spot in the sun and in wet soil to shallow waters. Moderately winter-hardy.
