[From "China in California: Dr. Wang at Quarryhill", by Darrel g.h. Schramm, pp. 8-9]
Dr. Wang aside, another Chinese rose we grow in California is ‘Fun Jwan Lo’ (modern spelling: ‘Fen Zhuang Lo’), also designated as ‘Odorata 44426’. According to the Chinese botanist Ma Yan, this old cultivar’s name means “The Women’s Dressing Building,” or, more romantically, “Milady’s Boudoir,” suggestive of “softly rumpled, silky pink blossoms.”
