Native to the harsh deserts of north-western Mexico and southern Arizona, it has evolved to thrive in some of the most unforgiving environments on earth, making it an incredibly resilient and rewarding plant to grow.\u003c\/p\u003e\n\u003cp data-start=\"634\" data-end=\"1005\"\u003eIts rich green stems are lined with neat rows of spines that catch the light beautifully, giving the plant a sculptural quality that looks equally at home in modern interiors, conservatories, garden rooms or bright office spaces.
