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.
Ecarlate. Hybrid Tea. (Boytard, 1907.) Scarlet-rose flowers of loose, informal shape and moderate size, borne in bewildering abundance throughout the whole season on strong, branching bushes with plentiful light green foliage almost immune to diseases. Very hardy and reliable.
A splendid, almost indispensable bright red Rose for massing, bedding, or low hedges about 3 feet high. While the flowers are not remarkable, it is a very satisfactory and long-lived plant, increasing in size and floriferousness each year. Plants in our nursery grounds over eight years old are especially fine.

Ecarlate (Boytard, 1907): very bright scarlet-crimson, semi-double, shapeless flowers, which do not blue but fade lighter. Tall, bushy plant which improves year by year. Preferred to 'Red-Letter Day' (A. Dickson & Sons, 1914) because of its better blooming, but some of the descendants of 'Red-Letter Day' may be still better. The most promising. are' K. of K' (A. Dickson & Sons, 1917), 'Red Cross' (A. Dickson & Sons, 1916), 'Red Star' (H. A. Verschuren & Sons, 1918), and 'Hawlmark Crimson' (A. Dickson & Sons, 1920).

Ecarlate (Hybrid Tea). (with picture.)
Ecarlate is listed as a Hybrid Tea in Rose catalogues; I howver believe it is a Hybrid China. Its habit, the forming of the blooms, all its characteristics justify this classification. The plant has a lush, well-branched, stocky habit, is very floriferous and willing and extraordinarily resistant against sickness and influence of weather. She can endure winter in not very cold regions without covering. The semi-double, medium sized blooms, mostly in clusters, are brilliant scarlet and of good effect.
Never yet have I seen any sicknesses in this rose. She can be very much recommended as an excellent, faithful group Rose.
An extensive group of Ecarlate was planted at the Rose Exhibition of Breslau in 1913, with great effect. F. Ries.
