Everywhere you travel in Morocco you see cacti, dotting the arid landscape endlessly. Not only does it have huge economic benefits, it is also used as fencing on farms and decoratively in gardens. The fruit called prickly pear or Barbary fig is exported widely plus sold on every single street corner for locals and tourists alike when in season. The seller, wearing gloves to the elbow, peels your thorn encrusted fruit for you. A prickly pear fence is very inexpensive and is a brillant deterrant to human intruders and stops animals wandering away. Very nasty to have a personal encounter I imagine !
