Bourbon Roses
The Bourbons are desirable old-fashioned Roses closely related to the Chinas. Many of them bloom continuously but a few are once-blooming only. There are both climbing and bedding types. Our list includes two of the finest old sorts and interesting, modern varieties. 
Kathleen Harrop. (A. Dickson & Sons, 1919.) Pale shell-pink, well-formed, very fragrant. Blooms freely in spring on a thornless, climbing plant.
A light-colored sport of the lovely Zephirine Drouhin, and especially handsome in combination with it. $1 each.
