This is an submerged aquatic plant that makes a good oxygenator.They are difficult to establish in a recently constructed water garden. Winter buds will sink to the bottom and arise again in spring with new growth. This species can be found in great abundance some years, and not at all other years.This plant is endangered in Italy as well as other places.
