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.
Constance Casson. Hybrid Tea. (B. R. Cant & Sons, 1920.) A very large pink and yellow flower, marked and shaded with apricot, gold, and copper. Many petals, good substance, and fragrant. A stout, dwarf plant, free flowering and quite healthy.
Much like Gorgeous, with heavier petals and more enduring color. A highly tinted garden Rose. Seldom mildews and seems very resistant to black-spot for a Rose of this type. $1.50 each.

General List. (130) Constance Casson (HT. B. R. Cant) F.3. Coppery pink, flushed and veined with apricot and yellow, large, double and globular. A very rich coloured variety and very free in blooming. This will make a splendid dwarf bedding rose. Growth is low, but not weak. Although of Pernetiana origin it does not show any signs of dying back so is included in the H.T.'s. Recommended.

A Trial of New Roses
British Introductions of 1920.
Constance Casson (Pernetiana, B. R. Cant and Sons).—A very strong grower, with large, globular blooms of bronze flushed yellow colour. The foliage is very fine, particularly the new growths. The blooms may be strong enough for exhibition, but their shape is inclined to be flat. It should make a splendid bedding Rose, and the colour is decidedly novel.
