Hardy Everblooming Rose
Admiral Schley
Named in honor of the hero of Santiago, and in every way worthy of that illustrious distinction.  Magnificent Hybrid Tea Rose, with flowers as finely formed as Meteor or Liberty.  Deliciously fragrant, and in color a beautiful deep crimson.  A strong grower, free bloomer, and a variety that should be grown in the home of every American citizen.  We predict for it that it will become one of the most famous of roses.  Price, 10 cents each; two year old plants, 30 cents each.

Admiral Schley. The Crimson Rose shown on the Colored Plate. It was raised by Mr. John Cook of Baltimore and named by him in honor of one of Maryland's favorite sons. This is essentially a Rose for the garden, ironclad in its resistance to all diseases, particularly mildew, that scourge of outdoor roses in this country. It blooms in the most luxurious abundance, and even in the hottest weather the flowers remain double. This variety is certain to be a great favorite. A large bed of it planted in the Pan-American grounds at Buffalo was a mass of bloom all season.
