Fig. 295.- Gray Goldenrod (Solidago nemoralis). X 1/4.
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.
