There are so many well-known Climbing Teas, Noisettes, and Climbing Hybrid Teas which give good results and from which bloom may be expected during the entire growing season, that it is not considered advisable to recommend as yet some of the newer European introductions of supposedly hardy roses which are put out as being of everblooming habit.
