Mammillaria prolifera, commonly known as Texas nipple cactus, is a perennial herbaceous succulent native to arid, rocky habitats such as desert scrub and limestone hills in Texas, Mexico, and the Caribbean. This cactus is particularly adapted to hot, dry environments. It typically forms dense clusters due to its numerous offshoots, which give it a small, round shape. Mammillaria prolifera reaches a modest size, usually not exceeding 6 inches (15 cm) in height and spreading to form clumps that can be quite wide. The plant is characterized by its cylindrical stems covered with nipple-like tubercles and small spines.

The Texas nipple cactus blooms from late spring to early summer, producing small, white to yellow flowers that are followed by attractive red, berry-like fruits. The flowers are not particularly showy, but they add a subtle charm to the plant’s appearance. In cultivation, this cactus is valued for its ease of maintenance and its ability to thrive in poor, well-drained soils with minimal water once established. It is often used in rock gardens, xeriscapes, and as a container plant. It requires full sun to light shade and is tolerant of high temperatures. While generally disease-free, it can be susceptible to root rot if overwatered. It is not known for being invasive and is a low-maintenance choice for gardeners interested in drought-tolerant plants.CC BY-SA 4.0
