Buff King Large-flowered Horvath setigera hybrid. Color of Flower: Amber and buff shafings, difficult to describe. Buds ovoid, deep amber colored, opening into large cup-shaped flowers which are produced on spur branches both on main stock and laterals, 12 to 15 inches long. This is the amber-colored form of Doubloons. Foliage: Glaucous green and healthy. Seldom affected by black spot or other Rose maladies. Hardiness: Can be successfully grown with protection in the colder regions where growing Roses heretofore has not been possible or exceedingly difficult. Size of Plant: Ultimate height 10 to 12 feet. Canes are very plentiful which is in part responsible for the tremendous amount of flowers produced.

The Recent Horvath Climbers
R. E. Shepherd, Medina, Ohio
Although Buff King will invariably winter-kill almost to the ground it rarely fails to produce a few very beautiful amber-buff blossoms of good form and on long stems. It, like Thor, deserves winter protection. The parentage is given simply as a "Setigera hybrid."

Proof of the Pudding.
Buff King HS. Buff. (Horvath, '39) ARA '39; PP '40, '41. Hamblin, Mass., says it is exactly as described and pictured in the catalogue; plants are as hardy as any LC, and flowers very desirable. Piester, Conn., (3 pl., 3 yr.), has strong growth with heavy canes but so far no bloom. Reed Va. (1 pl., 2 yr.), reports a healthy plant but the flowers so uninteresting that he did not bother to see if it has any fragrance. Lashley, Ohio, (1 pl., 2 yr.), declares it requires dusting to control black-spot. Ayres, Mich., (1 pl., 3 yr.), says that it has neither form nor fragrance and is not of real importance.

Proof of the Pudding.
Buff King HS. Buff. (Horvath, '39). ARA '39. We have a single report from McGinnes, Pa., (2 pl., 7 yr.), who considers it one of the most vigorous of the Climbers with varnished foliage and immense flowers similar to those of 'Golden Dawn', although of a deeper color. His plants have been very hardy.

R. Marion Hatton. New Roses in America.
His [M. H. Horvath's] first Setigera hybrid the Climber 'Doubloons' has become quite popular, and is now followed by the Climbers Buff King, 'Federation', 'Hercules', 'Mercurius', 'Polaris' and 'Thor'. These are all husky plants, with heavy canes 8 to 15 feet long, and bloom but once. 'Buff King' is a deep amber coloured form of 'Doubloons'.....
