Pincushion cactus are native to Canada, growing in Alberta, BC, and Saskatchewan prairies and semi-deserts. Our Xeriscaped front garden diorama features several species of Canadian and Siberian cactus. Yellow and pink pincushion are in full bloom right now – so if you like unusual flowers swing by with your camera to have a look. There will also be a plethora of Prickly Pear flowers out very soon. Note that cactus flowers are only out in full sun!
