NOMENCLATURE. German, spanische ladanum-cisten. Spanish,yara, xara. 

 Portuguese, estevao. 



USES. In the Aegean islands, the gum rockrose is one of the trees that provide 

 labdanum, a gummy, resinous extract used medically as an astringent, a decongestant, 

 and for healing wounds. The Greeks and the Circassians used it as very good protection 

 against malaria and even against plague. 



These two shrubs can be used as ornamentals in conservatories in the north of 

 France. In Provence, they thrive in open ground. 



Cultivation. The plants can be propagated from seeds, but since these often 

 don't ripen in the north of France, they have to be propagated from cuttings during the 

 summer. They take root at the end of six weeks. Rockroses kept in a conservatory require 

 little care. Free sandy soil with a little watering in winter is sufficient. When the cold 

 weather isn't severe, one can take a chance on leaving them out in the open.
