A variable but most elegant Aster everywhere common in dry soil along roadsides and in open woods, during August, September and October. The rather stout stem rises from two to four feet in height, and is either branched or simple. The thick-textured, long-oval, light green leaves are sometimes toothed. The upper ones are usually heart-shaped and clasp the stalk, while the lower ones taper into winged stems. The rays of the flower head number from fifteen to thirty, and are of a beautiful shade of blue or violet, rarely white. They are set around a yellow centre of disc florets. The heads are an inch broad, and they are closely set in a lovely terminal cluster. The Smooth Aster ranges from Maine and Ontario to Missouri, Pennsylvania and Louisiana.
