Aquatic Irish wildflowers
Irelands aquatic plants occupy a wide range of habitats, from clear streams and lakes to brackish fens, bog pools and drainage ditches. Some Irish waterways are badly affected with agricultural and forestry run-offs causing a harmful build-up of algae. Others remain clean and oxygenated, benefitting the health of both plant and fish life.
Below are some Irish wildflowers to be found growing in streams, rivers, marshes, bogs and ponds.
