Editor's footnote:  The Senior Editor, who loves hardy climbers, wonders why Mr. O'Neal does not mention the Walsh climbers - all truly hardy; mostly single, and of delightful forms as well of great vigour.  Seemingly they are almost "out", though excelling most of the newcomers in sheer beauty.  At Breeze Hill we are establishing a long hedge-fence of Walsh beauties, in his memory, including Paradise, Evangeline, Hiawatha, Milky Way, Wedding Bells, Excelsa, Troubadour, Sweetheart, Minnehaha, and others. Notice the pleasant names!

Wichuraiana Hybrid Roses
Sweetheart
The buds of the Sweetheart Rose are of a dainty bright pink, changing to white when fully expanded, and possess a delicious fragrance. The blooms are large and double and the plant, which flowers abundantly, is sturdy, healthy, vigorous and hardy. The foliage is dark, glossy green. Wherever a pink Rose is desired, especially for climbing over an arbor or trellis, the Sweetheart may be recommended. (See illustration, page 61.)

Wichuraiana Ramblers. By Dr. A. H. Williams, Vice-President N.R.S.
The wichuraiana Ramblers fall naturally into two well defined groups:
II. The Late, composed of those whose main flowering season lies in the month of July. They mostly have a strain of multiflora in their parentage. The trusses are usually very large, consisting often of an immense number of small flowers, which may be either singles or double rosettes.
Late Flowering Double Varieties.
Sweetheart is of similar growth and colouring [to Carissima]; very fragrant.
