Single Roses
These are Hybrid Tea Roses with single or almost single flowers, and require the same culture and care as the other Hybrid Teas. They are often called the "Irish Singles", although they are not all of Irish origin. The buds are especially fine, but the open flowers are rather perishable although they are very freely produced.

"New Roses for the Garden" by Charles E. F. Gersdorff
A new line of Roses developed and described by Captain George C. Thomas, Jr. in the "American Rose Annual" for 1920 must be mentioned although I have not had opportunity for any personal observation of these varieties. However, the fact that they have been admired by others and have passed successfully the rigid tests conducted at the Rose Test Garden, Portland, Oregon, and have been produced by an amateur whose standard of excellence is very high and whose ability in judging the merits of Roses is well known, leads me to believe that one would not go far wrong in acquiring these varieties. I have in mind the following: [...] Bloomfield Perpetual, a perpetual blooming semi-climber suitable for hedges, carries bloom from spring to frost, having the perfume of the Cherokee Rose and its color. All four were sent out in 1920 by Bobbink & Atkins.
