Pelecyphora aselliformis is an unusual and highly sought-after succulent native to the Mexican state of San Luis Potosí. It is a small, globular cactus with a diameter of only about 2 inches (5 cm). Its thick, green stem is covered in tiny white hairs and has five to eight ribs that are lined with small spines. The plant produces flowers that are yellowish-green in color and have six petals. These flowers bloom from late spring to early summer and attract pollinators such as bees, butterflies, and hummingbirds. The flowers eventually give way to small fruits that contain the plant's seeds. The leaves of Pelecyphora aselliformis are fleshy and spoon-shaped, growing up to 1 inch (2.5 cm) long. They have smooth edges and are usually light green or grayish-green in color. This succulent requires well-draining soil and plenty of sunlight for optimal growth. It should be watered regularly during its active growing season but allowed to dry out completely between waterings during its dormant period in winter months. Overwatering can lead to root rot so it's important not to overwater this species. Pelecyphora aselliformis has been cultivated since the late 19th century by cactus enthusiasts who appreciate its unique appearance and low maintenance requirements. Today it remains popular among collectors due to its rarity, making it an interesting addition to any succulent collection!
