Each areole bears 5 to 7 radial spines growing up to 2.4 inches (6 cm) long.
During the summer, the plant produces beautiful lavender to pink flowers from the areoles at the top of the stems. It blooms quite profusely, even young. The flowers are funnel-shaped and can reach up to 2.4 inches (6 cm) in length. The red fruits are cylindrical and about 1 inch (2.5 cm) long and 0.4 inch (1 cm) in diameter.
Gymnocalycium anisitsii var. tucavocense is native to Bolivia. It grows in open areas with the protection of low bushes in the Tucavaca Valley and adjacent areas in the Santa Cruz department.
How to Grow and Care for Gymnocalycium anisitsii var. tucavocense
Light: During the hottest months, this cactus needs some protection from direct sunlight. However, excessive shading will result in the loss of flowers.
Soil: Having soil with good drainage is most important for a healthy Gymnocalycium anisitsii var. tucavocense. You can use commercial soil for cacti or make your own mix.
Temperature: This cactus can tolerate high temperatures but is not a cold-hardy plant. So, if there is a risk of freezing temperatures, bring it indoors. It grows best in USDA Plant Hardiness Zones 9b to 11b, with average minimum winter temperatures ranging from 25 to 50 °F (-3.9 to 10 °C).
Watering: During the growing season, water Gymnocalycium anisitsii var. tucavocense frequently, but allow the soil to completely dry out before watering again. In the winter, when it goes dormant, cut back on watering.
Fertilizing: While it does not need much fertilizing, giving it some extra nutrients occasionally keeps the plant healthy and prolongs the time for repotting. During the winter, there is no need to fertilize, as the plant is not actively growing.
