Densely packed white spines on red spine silver torch cactus (Cleistocactus juyjuyensis) give this columnar cactus a silvery appearance throughout the year. Brilliant red-orange tubular flowers are produced in large numbers in April. This native of South America branches at ground level to produce a "forest" of upright stems. Like other cacti, this plant requires high light intensity, low humidity, warm temperatures, and exceptionally well-drained potting medium that is infrequently watered.
