In some sections of the country, this plant has been regarded as a troublesome weed, and one that is not easily discouraged by frequent attempts to eradicate it from cultivated fields, which it has overrun since its introduction from Europe. The flower lover however, will always welcome it along our highways and byways, inasmuch as our flora is not over-toned with true blues. The stout, bristly-haired biennial stalk is much branched, and its light green surface is dotted with red or purple. The alternating rough and hairy, oblong or lance-shaped leaves are toothless and clasp the stalk, and the lower ones are narrowed into short stems. The numerous, brilliant blue, tubular, funnel-formed flowers are unequally five-lobed. The latter are rounded and spreading. They are at first bright blue, varying to reddish purple. The five slender stamens and the pistil are rosy tinted, and project beyond the corolla, adding much to the general fuzziness of the plant. The flower buds are pink before they finally expand, and the numerous buds are closely arranged in a double one-sided row along the ends of the branches which are tightly curled. A few flowers on each cluster open at a time, as the stem gradually straightens. These floral clusters are closely grouped on the stalk, and at a distance from the large, thick, clumsy spike. The entire plant is so bristly that it is not likely to become a popular bouquet flower. It is found from Canada to Virginia and Nebraska, from July to September.
