- Hardy to USDA Zone (7) 8 From a cross of C. monspeliensis × C. salviifolius and selected by Jean-Pierre Demoly.
- Robert G. Page (Cistus & Halimium Website) states that "plants sold under this name are rarely true to name. The name has long been misapplied to Cistus 'Enigma' (recently named by me) and other hybrids."
