Ground iw is characterized by a small blue flower, and a kidney-shaped leaf that 

 gives off a minty odor when crushed. Ground ivy develops long runners that often 

 grow beneath the grass. These runners may be raked or pulled out to keep the plant 

 from running rampant. Chemical treatment with silvex, MCPP, or dicamba either 

 alone or in combination with 2,4-D used at the rates recommended on the container 

 should offer effective control although repeat applications may be needed for com- 

 plete eradication.
