Geographic Distribution and Habitat –
The mare’s-tail is a common and widespread plant in Eurasia and North America, mainly in the northeast but also in New Mexico and Arizona. In Eurasia it is quite common in fresh basins on mountain ranges, in non-acidic waters.
In Italy it is common but rarer in all northern regions (except in Val d’Aosta and Liguria) and in the Tyrrhenian regions up to Campania.
Its habitat is that of clear, stagnant or slowly flowing waters, up to 2 m deep, from sea level to about 600 m.
Hippuris vulgaris that grows in shallow muddy waters, rooting on the seabed and with most of the leaves above the surface.
It has rhizomes and the leaves are verticillate of different shape depending on whether they have emerged or submerged.
The stems are solid and unbranched and can reach 60 cm in height.
The plant is dioecious; the flowers are tiny, of a brownish red color, with a single whorl of tepals (perigonium).
The fruit is a 2–3 mm elliptical achene.
Hippuris vulgaris is a very useful marsh plant for phytoremediation.
It is advisable to plant it with a planting depth between the rhizome and the water surface from -5 to -15 cm.
The best exposure is in full direct sun for at least 6 hours a day.
