Chamaerops humilis var. cerifera
Blue Mediterranean fan Palm

This palm, which grows in the Atlas mountains in Morocco up to 1700m, offers all the virtues a palm enthusiast from outside the tropics could wish for. It is as robust and adaptable as its regular green relative and happy in a wide range of conditions, tolerating extremes of cold and damp as well as heat and drought or full sun to shade. However, its main attraction is the colour of its leaves: an intense blue-silver (and here we don't mean the silvery colour as seen on the undersides of the leaves of many Chamaerops) on the upper as well as the lower surface of the leafblade. Indeed it is as blue as Brahea armata.
