Mammillaria gracilis, is a small cactus with bright green cylindrical stems densely covered with white spines. It offsets freely to form large clumps. The stems are up to 5.2 inches (13 cm) long and 1.2 inches (3 cm) in diameter. They fall off easily but readily reroot. All spines are usually radial, but occasionally there are 1 to 5 dark-brown central spines. Flowers are creamy to pale yellow with pinkish or brownish mid-stripe and usually appear in spring but also in late summer and fall. They are up to 0.5 inches (1.3 cm) long and nearly equal in diameter.
To encourage better flowering, allow the plants to enjoy a cooling period in the winter and suspend watering. Unlike many other cacti, which use their ribs as storage devices, Mammillaria features raised tubercles, from which spines emerge. When you water, the tubercles will expand to allow for increased water storage. The flowers appear from these tubercles' axils on the previous year's growth, which accounts for their interesting halo effect. The cactus mustn't be exposed to prolonged dampness and sitting water. Never let your cactus sit in a dish of water. Lastly, make sure to fertilize during the growing season for the best results.
PLEASE NOTE: this form of cacti are very fragile and pieces break off very easily. We highly recommend picking this item up if possible.
