5-7cm Gymnocalycium bodenbenderianum variegated（rootless）

Gymnocalycium bodenbenderianum is a striking cactus variety known for its distinctive dark spines and compact growth habit. This slow-growing species features a solitary, globular stem that gradually develops a flattened appearance with age. The plant's most notable characteristic is its jet-black to dark brown spines that create a dramatic contrast against the blue-green to gray-green epidermis, giving it a unique "black crown" appearance.
