Cyclopedia of American horticulture, comprising suggestions for cultivation of horticultural plants, descriptions of the species of fruits, vegetables, flowers, and ornamental plants sold in the United States and Canada, together with geographical and biographical sketches. Gardening. 114 ASTER ASTER of the cyanic series—shades of blue, red, pink and pur- ple. The modern evolution of the plant is in the direc- tion of habit, and form of flower. Some type varies— generally rather suddenly and without apparent cause— into some novel form, still retaining its accustomed color. The florist fixes the variation by breeding from the best and most stable plants, and soon other colors appear, until he finally obtains the entire range of color in the species. So it happens that there are various well marked races or types, each of which has its full and independent range of colors. The Comet type (with very flat rays), now one of the most deserving of the China Asters, illustrates these statements admirably. The Comet form—the loose, open flower with long, strap- like rays—appeared upon the market about 1886 or 1887, with a flower of a, dull white overlaid with pink. The pink tended to fade out after the flower opened, leaving the color an unwashed white. The rose-colored Comet next appeared, and the bhie was introduced in 1890. The first clear white was introduced in America in 1892, coming from Vilmorin, of Paris, and the China Aster had reached its greatest artistic perfection. It is impossible to construct a satisfactory olassifloa- tion of the China Asters. It is no longer practicable to classify the varieties by color. Neither is it feasible to classify them upon habit or stature of plant, for several of the best marked types run into both tall and dwarf forms. Vilmorin, however, still divides the varieties into two groups, the pyramidal growers, and the non- pyramidal growers. The most elaborate classification is that proposed by Barron, from a study of ext
