The Peruvian Apple Cactus (Cereus peruvianus), also known as the Queen of the Night, is a striking columnar cactus that thrives in Tucson's desert climate, adding height and architectural elegance to any landscape. This fast-growing cactus features blue-green ribbed stems with sparse spines and produces stunning, nocturnal white flowers that bloom in summer, followed by edible, sweet-tasting fruits. Highly drought-tolerant and low-maintenance, it excels as a focal point in xeriscapes, along walls, or in large containers. Its dramatic form and versatility make the Peruvian Apple Cactus a standout choice for creating bold, water-wise designs in Tucson gardens.
