Tephrocactus articulata cv. papyracantha is a small cactus native to Western Argentina. The gray-green cactus has jointed stems approximately 2 inches (5 cm) long by 1.25 inches (3 cm) wide and will reach 12 inches (30 cm) in height. One to four white papery spines arise from each tubercle and are 1.5 inches (4 cm) long. They are easy to culture and make an interesting cactus in any collection.
Blooming Time: In spring, the 0.5 inch (1.5 cm) yellow flowers appear and are followed by 2-inch (5 cm) fruits that are brown.
Culture: Tephrocactus articulata cv. papyracantha need full sun and a well-drained soil mix. In the greenhouse, we use a soil mix consisting of 2 parts sand to 2 parts loam with small gravel added to insure good drainage. In the spring and summer, the plants are watered and allowed to thoroughly dry before watering again. They are fertilized on a monthly basis with a balanced fertilizer during the growing season. During the winter months, the temperatures are dropped to 50°F (10°C), and water is restricted.
Propagation: Tephrocactus articulata cv. papyracantha is propagated by cuttings or by seed in the spring.
