I have found a rampant climbing rose on a friend's property that I believe may be this rose or one very, very similar to it. It has a sweet musk rose fragrance, moderate to strong. The blooms are identical to the ones pictured. The buds are small, soft pastel pink before opening to white blushed with pink and a prominent boss of yellow stamens. It blooms in large cascades of trusses. The rose is at least 50-60 years old in its current location with a "trunk" the size of a tree. It has naturally scrambled 20+ ft into a crepe myrtle tree. It features small, long oval hips, bright red (very much like a hybrid musk). The foliage and canes differ quite a bit from any hybrid wichuranas or hybrid multifloras I've seen. The plant appears completely disease free- no fungal issues of any kind. There is a Dorothy Perkins type rambler about 15ft away with obvious spotty mildew. I'm going to take some photos and post them in the next couple of days.

Update 04.22.2012 with photos as promised. I cannot find any rose in the HMF database other than Suan Juan Musk that matches this found sample. The buds are distinctly single, small, fragrant. The foliage and hips are very moschata-like.
