Hottonia palustris, alsowater violet orfeatherfoil, is anaquatic plant in the familyPrimulaceae.
The plant has a stem reaching up to 80 centimetres (30 in) in height. Its basal roots are buried in the underlying mud, while other silvery, shiny roots dangle freely in the water. The leaves are deeply divided as far as the central vein, like the teeth of a double comb, and are completely submerged, but can surface after a drastic fall in water level. The leaves arealternate or connected to the stem in more or less regularwhorls. The flowers arehermaphrodite and pollinated by insects andcleistogamy; they appear from May to June. The plant is self-fertile.[citation needed]
Featherfoil is found inEurope and northernAsia. The species epithetpalustris is Latin for "of the marsh" and indicates its common habitat.[1]
Naturally abog ormarsh plant, most specimens sold have been grown emersed and must be submerged in stages in the aquarium to encourage them to adapt and form submerse leaves. Featherfoil can be kept in a cool or tropical aquarium. A good substrate, light and, if possible, additional CO2 are beneficial. It can be grown in or around ponds, for which it is considered a good oxygenator. Its bushy leaves provide protection for fish andfry. It can grow floating as well, or exposed to sun.[citation needed]
