Creeping jenny is a native of Great Britain and much of Europe. It was first introduced as an ornamental. This rapidly growing perennial reproduces by seed as well as through a creeping growth habit of the stems. The stem creeps along the ground, rooting at each node when it gets the opportunity. The plant tends to cover the ground with a mat of low-growing vegetation, excluding other herbaceous vegetation. Its ability to root at nodes enables it to cover large areas. <www.invasive.org>
In 100 Years of Change in the Distribution of Common Indiana Weeds by William and Edith Overlease (2002) reported that creeping jenny was found in Indiana in 1899 (Coulter’s Catalogue of Indiana Plants) in the following counties: Clark, Franklin, Jefferson, Knox, Monroe, and Posey. Coulter noted that creeping jenny was “found only in the southern part of the state”.
In 1940 (Deam’s Flora) and it was noted that “creeping jenny was frequent in low ground along streams, ditches, roadsides, and elsewhere.” Creeping jenny was found in the following 30 counties: Allen, Cass, Clark, Clay, Dearborn, Elkhart, Fountain, Gibson, Greene, Harrison, Hendricks, Howard, Jasper, Jefferson, Jennings, Johnson, La Porte, Lawrence, Marion, Monroe, Montgomery, Newton, Parke, Putnam, Starke, Steuben, Sullivan, Tippecanoe, Wayne, and Whitely.
