Barney is a compact own-root mihanovichii with swollen, pebbled ribs washed in dusky plum over olive green and set off by warm copper spines.

Barney stands out immediately for its dense, sculptural body: a low, rounded plant built from thick, knuckled ribs that read almost like stacked pebbles. The surface shows a fine matte texture, with dusky plum to wine-red blushing spread across an olive-green base, creating a moody, weathered palette that feels especially collector-forward rather than flashy. Creamy areoles punctuate each rib, and the spination is spare but expressive—slender, amber-copper spines projecting cleanly from the body and sharpening the overall silhouette. As presented here, Barney is own-root and notably compact, with a tight central crown and a strongly contoured, almost tessellated rib structure that gives the plant a muscular, miniature presence. The contrast between the muted body tones, pale areoles, and fine warm spines is what makes this clone memorable: it has the look of a small cactus carved from oxidized stone, then finished with copper needles.
