Dormant 2-Year-Old Field-Grown Rose Bushes
Francis Scott Key (Hybrid Tea) (See Front Cover)—This American rose named in honor of the author of our national anthem, is a credit to its name. Immensely popular because of its glowing colors, remarkable size, fullness, and perfection of form. The color is a rich, glowing scarlet, with darker shadings, becoming darker as the flower ages. A continuous bloomer, producing its immense blooms on stout stems in great profusion. The growth is excellent and the foliage heavy, little troubled with disease. Very hardy. All sections of the country report excellent results with this remarkable rose.
