Every patriotic citizen of the United States should know this historic plant, because a brewing of its leaves was used as a substitute for tea by the American troops during the Revolution. It was employed at about the same time, too, when old King George the Third unwittingly assisted in creating the greatest tea-party at Boston Harbour that the world has ever known. The astringent roots possess some medicinal qualities, and they also yield a brown dye. It is a small, shrubby, branching species, with a whitish, powdery bloom, and its leafy stalk rises two or three feet high from a deep, reddish root. The pointed, oval leaf is set alternately upon the stalk with short stems. The hairy surface is creased with three ribs and its edges are finely toothed. Numerous tiny, white or creamy white flowers are densely crowded into oblong, terminal clusters. They are composed of five petals, and have long, slender stems, and possess a faint fragrance. It ranges from Ontario and Manitoba to Florida and Texas, in dry, open woods, where it blossoms from May to July.
