During July and August we find the Blue Vervain with every one of its slender, upright branches terminating in numerous long, beady, rocket-like, flowering spikes, each so lengthened and regulated as to form an elaborate, equally balanced, floral candelabra. It is a handsome perennial, growing from three to seven feet high in moist fields and meadows, or along railroads and highways. The stout, rough, leafy stalk is four-sided and grooved, and is often stained with red. The opposite lance-shaped leaves are irregularly double-toothed and taper-pointed, with noticeable veins. They are short-stemmed and rough surfaced, and the lower ones are sometimes lobed or arrow-shaped at the base. The five-lobed tubular flowers are very small, and several open at a time in a single circle as they mount the extending, purple-stained spike. They are deep purplish-blue in colour, and have a pistil and two pairs of stamens. As the flowers continue to blossom toward the top of the spike, they are succeeded by ripening seed enclosed within the overlapping, purplish calyx, which lends much to the attractiveness of the royal colour scheme. Vervain is also known as the Holy Herb, and was one of the religious plants of the Druids. Long, long ago, Vervain was held sacred to Thor, the god of thunder, and like other plants connected with lightning, it was supposed to possess peculiar influences upon the eyesight. It is also said to have been found growing upon the Mount of Calvary when Jesus died. On account of its mystic virtues, it was formerly much used for stimulating affections and charms. It was reputed to break the power of witches. In France, it is gathered under certain changes of the moon with secret incantations, after which it is supposed to accomplish remarkable cures. Bridal wreaths made of Vervain are used in Germany. It was one of the most important assets of the old herb doctors who were called "Simplers," and who professed to cure everything that flesh was heir to. Virgil and Shakespeare both mention Vervain in their writings. The Wild Hyssop, as it is sometimes called, is found from Canada to Florida, Nebraska and New Mexico.
