Ferocactus robustus, also known as the clump barrel cactus, is a species of cactus in the family Cactaceae. The main stems of the plant are globus to cylindrical and tend to clump together at the base. Ferocactus robustus is native to Mexico, where it is found in the states of Durango and Jalisco. Each stem grows up to 3 to 6 inches in diameter and only a couple inches tall. Each stem is covered in short sharp brown spines protruding from each white areole. Ferocactus robustus bloom during spring and autumn with large long lasting yellow flowers. F. robustus is grown as an ornamental plant for its medium to small size and drought tolerance. F. robustus grows best in full sun to partial shade while sitting in well-draining soils. Water the plant adequately during summer and keep dry during winter as it is prone to rot. Allow the soil to completely dry out in between waterings. USDA plant hardiness zones 9a to 12a. Ferocactus robustus seeds require consistent moisture and humidity to germinate, but the soil should not remain soaking wet. Cloning boxes, ziplock bags, and other containers that retain humidity are ideal to store sown pots. Use a well-draining sterilized soil mix. Seeds should be sown directly on top of the potting mixture. Germinating pots should be kept indoors, out of extreme light and heat. Ideal germination temperatures range from 75°F to 85°F. Germination typically takes 2 to 4 weeks to occur. Even with optimal conditions, germination may be slow and sporadic.
