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.
