Like you, Fleur, I hesitated to answer as Sarcopoterium is hardly considered to be an ornamental plant here. It covers the hillsides and makes walking off any beaten track rather hazardous to say the least. The book 'Trees and Shrubs in Cyprus' describes it as; 'An indigenous species, occuring in garigue and impoverished areas, where frequently it is the dominant species.' I would think it should germinate very easily from seed, it is one of the first plants to recolonise following fires, for example.
