Stinking Chamomile Eclipta prostrata

False daisy is a short-lived perennial to annual in the Asteraceae (daisy) family.  This plant is found in warm temperate to tropical areas worldwide and has prostrate or ascending stems. Stems are purplish and can root at the nodes. Plants germinate in late spring through summer. This species can be found growing in ditches, near rivers and swamps and also in drain holes of containers.  

Plants can reach over 3 feet in height and width given sufficient space. Typically, the plant will flower in summer and early fall then die after frost.  Depending on the location, it can bloom year round.  Seed heads are white and ripening fruit is button-like. Although some preemergence herbicides will suppress this weed, it is difficult achieving high levels of control. Hand weeding large plants is difficult due to the extensive root growth and adventitious rooting of stems. 

This plant prefers full or partial sun, wet to mesic conditions, and loamy or mucky soils and is most often found in disturbed wetland habitats. 

The leaves contain nicotine which acts as an insecticide. It has been used in herbal medicine worldwide. In some parts of this country, it is considered a weed and in some areas, it is considered an endangered species.  

The weak, spreading habit of this plant allows the stems to come in contact with the ground, thereby rooting at the nodes can occur.
