[From the article "Multiflora Ramblers" by Edward K. Butler, Jamaica Plain, Mass.]
White Rambler. (Pemberton, 1914.) Has not flowered with me yet but is described in the "Select List of Roses" of the National Society as pure white in color, very vigorous, and the best white rambler. It is a late bloomer, and the foliage is mildew-proof. A large-flowered, early-blooming whie rambler is very much needed at present.

Pemberton's White Rambler is a dead white with very double flowers. Being of the multiflora type, it would associate finely with the old Crimson Rambler.
