Commodities Affected:
Forestry and Natural Areas

 

Threat:

White sweet clover is native to Europe and Asia. These clovers readily invade open habitats and already have successfully exploited many Midwestern native prairies and open, unflooded communities. Areas most likely to contain sweet clover include roadsides, abandoned fields, railroad ballasts, pastures and any unflooded, open natural community such as a prairie.  Note:  Plant with caution – plant only for soil fertility and do not allow to produce seed; do not plant for forage, beekeeping, or other purposes.

 

Distribution:

In 100 Years of Change in the Distribution of Common Indiana Weeds by William and Edith Overlease (2002) reported that white sweet clover was recorded in Indiana in 1899 (Coulter’s Catalogue of Indiana Plants) in the following counties: Cass, Clark, Dearborn, Fayette, Franklin, Gibson, Jefferson, Kosciusko, Noble, Posey, Putnam, Randolph Steuben, Tippecanoe, Vigo and Wayne. Coulter noted that white sweet clover was “extremely abundant in waster places and cultivated fields throughout the state”.  In 1940 (Deam’s Flora) white sweet clover was recorded in: Crawford, Dearborn, Franklin, Gibson, Hancock, Harrison, Henry, Jasper, Jefferson,  Jennings,  Lake, Lawrence, Marion, Monroe, Montgomery, Morgan, Newton, Ohio, Parke, Porter, Putnam, Ripley, Shelby, Switzerland, Tippecanoe.  Dean noted that “this species has been sown for pasture and fodder and has abundantly escaped in all parts of the state.”   In 2002 Overlease recorded white sweet clover in the all 92 counties in Indiana.  Overlease noted that “it is locally common to locally abundant where found.”

 

In 100 Years of Change in the Distribution of Common Indiana Weeds by William and Edith Overlease (2002) reported that yellow sweet clover was recorded in Indiana in 1899 (Coulter’s Catalogue of Indiana Plants) in the following counties: Dearborn, Decatur, Fayette, Knox, Marion, Shelby, Tippecanoe, and Vigo. Coulter noted that yellow sweet clover was “not nearly as abundant as white sweet clover”.  In 1940 (Deam’s Flora) yellow sweet clover was recorded in: Allen, Benton, Blackford, Boone, Clark, Clay, Crawford, Dearborn, Franklin, Gibson, Grant, Greene, Harrison, Henry, Huntington, Jasper, Jefferson, Knox, Kosciusko, LaGrange, Lake, Martin, Monroe, Montgomery, Newton, Noble, Owen, Parke, Porter, Posey, Putnam, Steuben, Sullivan, Vanderburgh, White, and Whitely.  Dean noted that “this species has been sown for pasture and fodder and has abundantly escaped in all parts of the state.  It is much more aggressive than white sweet clover”.   In 2002 Overlease recorded yellow sweet clover in the all 92 counties in Indiana.  Overlease noted that “it is locally common to locally abundant where found”.
