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.
Mrs. Calvin Coolidge. Hybrid Tea. (U.S. Cut-Flower Co., 1924.) Clear buff-yellow flowers, suffused with orange in the center; of medium size, well formed, double, and of some fragrance.
A sport of Ophelia, resembling that variety somewhat, except in color. A much better Rose indoors than in the open ground. Roselandia and Golden Ophelia are much better Roses of similar appearance.
