Myrtillocactus geometrizans 'Fukurokuryuzinboku' is a strange cactus with upright, glaucous stems, each with 5 to 8 unusual ribs lined with tubercles that resemble women's breasts. The stems grow up to 14.8 feet (4.5 m) tall and 4 inches (10 cm) in diameter, usually solitary or sometimes with a few branches. Each areole may have up to 9, but they typically have 3 to 5 short spines.T hey are semi-hardy, so ensure your Myrtillocactus are not exposed to temperatures below 25°F (-4°C), or they may die. Nevertheless, it is good never to let nighttime temperatures fall below 50°F (10°C). In the summer, place Myrtillocactus in the sunshine (indoors or outdoors). In the winter, find a cooler, light spot. That will allow it to go into next spring well-rested, making it more likely to flower. This easy-care plant doesn't want a lot of water. Allow the soil to dry out before you give it another drink. Keep the soil completely dry in winter. Treat it to special cactus food monthly in the spring and summer.
