Photo (courtesy of J. Windham) of a clone of Ralph Moore's putative R. soulieana, showing stem and leaf color. The archetype is generally regarded as having grayish foliage and a grayish bloom covering the young stems, which appear to be lacking in this particular cultivar. As noted in comments by Kim Rupert, this, Ralph Moore's cultivar, also has been credited with creating re-blooming seedlings.
This thing is an absolute thug in my Central Texas garden. It shoots out ridiculously long, thin whips of over 20 feet which I have attempted to confine to the support of a crepe myrtle tree, from whence it dangles wickedly hooked limbs to fish for innocent gardeners trying to tend their plants. (I.e. Breeding stock only!)
