Some native wetland plants include arrow arum, soft rush, pickerelweed, marsh hibiscus and button bush. Specific wetland plants differ according to whether the wetland is a marsh, swamp, bog or fen. These plants also vary depending on the type of water system, be it a marine, lacustrine, estuarine or riverine system. Plants that thrive in marine wetlands are adapted to salt water, while riverine wetland plants need fresh water.
