COMPOSITAE (COMPOSITE FAMILY) 425 



Its stoloniferous habit causes this weed to form dense patches, 

 choking out all intervening growth. Stems usually tufted, from a 

 thick, woody root, six inches to a foot high, stout, rigid, clothed 

 with soft, velvety gray hair. Leaves alternate, thick, firm, also 

 velvety-hairy, the lower ones spatulate, three-nerved, wavy-edged, 

 tapering to petioles ; the upper ones much smaller, acute, entire, 

 and sessile. Panicles rather narrow and racemose, the branchlets 

 held nearly erect, making the cluster compact and not one-sided ; 

 heads small, very bright yellow. Achenes downy-hairy, with fine, 

 bristly pappus. 



Means of control the same as for Gray Goldenrod.
