British Golden-rod is a member of the large composite genus Solidago, which is chiefly North American. The golden-rods are erect plants, little branched, and often somewhat woody at the base. The foliage is various, usually somewhat lanceolate in shape, and sometimes conspicuously veined. The tiny heads have one series of white or yellow ray-flowers, and are gathered into various forms of inflorescence, often of a massive character; they appear in late summer and early autumn. Although of no commercial value (except as forage for sheep) the golden-rods are conspicuous for their bright color, especially as they are apt to grow in huge colonies in fields and along roadsides.
