Facts

German hedge-nettle is native to Europe, northern Africa and western Asia, and is a very occasional visitor to parts of eastern North America. In New England it has been collected only in Rhode Island. The leaves of this plant, covered with long hairs, were once used to dress wounds.

leaf blades cuneate at the base, the marginal teeth obscured by dense pubescence, the upper surface white to gray-white with dense tomentum, and calyx lobes largely concealed by pubescence of inflorescence (vs. S. germanica, with leaf blades truncate to cordate at the base, the marginal teeth evident, the upper surface gray-green with merely moderately dense tomentum, and calyx lobes projecting beyond pubescence of inflorescence and more evident).
