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.
Comtesse De Cassagne. Hybrid Tea. (M. Guillot, 1919.) Outside petals ivory-yellow, inside coppery pink; scented, very double flowers. Plant vigorous and a steady bloomer.
An attractive Rose of variable color, often clear yellow. Petals wide and well shaped. Reminds us very much of the splendid Miss Willmott but has more color, especially at the tips of the petals. We think a lot of this Rose.
