Wetlands plants are an important part of the ecosystem, providing food and shelter for many species of animals and birds. Two common wetland plants are SEDGE (5 letters) and REED (4 letters). SEDGE is a grass-like plant that grows in shallow water or on wet soil, while REED is a tall, slender grass-like plant that grows in shallow water. Both plants provide food and shelter for wildlife, as well as helping to prevent erosion and improve water quality.
