Creeping Water Primrose:

Creeping water primrose is a perennial plant that can grow in wet soil as well as float out onto the water.  Its leaves are a reddish-green and are 2” long and ½” to 1” in diameter.  The plant produces small yellow flowers that are 1” to 2 “ in diameter.  This is an invasive species that forms extensive mats and will deter water flow and limit shoreline activities.  It is used as an ornamental aquatic plant and improper use and disposal has lead to its spread in waterways.  Creeping water primrose is spread by seeds and plant fragments that are carried by boats, water, wind, and wildlife.  It can be controlled using a 2,4 D, Diquat, or Glyphosate herbicide.
