Everblooming Roses
The so-called Everblooming Roses include the Hybrid Tea and Pernetiana groups. They do not bloom all the time, but if kept healthy and growing steadily, one crop of flowers succeeds another at brief intervals.
Jacques Porcher. Hybrid Tea. (P. Guillot, 1914.) A light-colored Rose, combining delicately blended tints of carmine, saffron, and deep yellow; well shaped and mildly fragrant. Strong, upright growth, with foliage almost immune to disease, and very free flowering.
One of the best all-round garden Roses, yielding a profusion of attractive, but somewhat variable flowers, usually of cutting quality. Especially valuable for its resistance to black-spot and mildew, even under adverse conditions.
