General List. Wichuraiana Class. Excelsa (Walsh 1908) 6. Double, bright scarlet flowers, produced in clusters. Much more satisfactory than 'Crimson Rambler', as it does not mildew as a rule.

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!

....though it is a remarkable fact that many species and garden hybrids which flower late in the season mature their seeds quickly and ripen them well, e.g. Wichuraiana, Caudata, Banksiopsis, Hiawatha, Excelsa, etc.

EXCELSA. M. H. Walsh, 1909. An exceedingly vigorous Wichuraiana that was high-pressured into great popularity to replace Crimson Rambler, which it was wholly unfit to do. Its flowers are rosy crimson instead of scarlet, and very uncertain in shade, for many clusters have a disreputable, faded look. The foliage is so extremely subject to mildew that it is a pest. Bonfire and Fernand Rabier are ever so much better.
