Trichocereus bridgesii Montrose (TBM) Clone B—affectionately known as the Short Form Penis Cactus.

This genetic mutation completely throws out the rulebook. Instead of growing into a standard ribbed pillar, it produces smooth, dome-tipped, glaucous blue-green segments that top out at 3 to 6 inches. It’s completely spineless up top, throwing long, fierce honey-yellow spines only at the base of its joints.

Because it’s a prolific "pupper," it continuously stacks new segments to form a dense, highly sculptural, compact cluster over time. It’s tough, heavily resilient, fast-growing, and an absolute cornerstone for any serious cactus library.
