Whitman Cross. A short hedge of 'Hauff', 'Lessing', 'Schiller', and 'Schubert' is a joy to behold in June as a mass of white, produced by a multitude of small flowers showing shades of pink or yellow on close examination. These varieties vary in value of foliage. 'Hauff' and 'Lessing' losing a large part of theirs in summer, except on the long, new shoots. The many brown hips, which last until winter, atone in part for the loss of leaves. Recurrent bloom is largely on the ends of the vigorous shoots and appears until late in autumn. Perhaps the last-mentioned sorts would be more successful as climbers.

Growing and Showing Climbing Roses. by A. J. Fish, New Bedford, Mass.
There are really fewer colors that clash among climbing roses than in the bush roses. The Blue Rambler is the worst, and should only be used when surrounded by white, or, what is still better, set up by itself as a novelty. 'Hauff', a variety intermediate in color between Blue Rambler and Crimson Rambler, should not be exhibited.

[From the article "Multiflora Ramblers" by Edward K. Butler, Jamaica Plain, Mass.]
...Of the newer varieties the following are well worth trying: Andreas Hofer, Blanche Frowein, Elsie, Germaine Lacroix, Grafin Ada Bredow, Grafin Chotek, Hauff, Mme. Ghys, Marie-Jeanne, Starlight, and Steil Rambler. I know of no single catalogue that includes all of these, but most of them can be found in those of Bobbink & Atkins, Rutherford, N. J., who have an admirable list, and of Hugh Dickson, Ltd., Belfast, Ireland.
