🌵 Tephrocactus alexanderi 3

Chunky stone-like segments and rugged desert texture make Tephrocactus alexanderi a weird and wonderful cactus collector favorite.

With rounded, stacked segments that resemble smooth desert stones or tiny cactus eggs, Tephrocactus alexanderi looks like something shaped by wind, time, and pure chaos. Its soft gray-green color and minimal spines give it a sculptural, almost prehistoric appearance that stands out instantly in any cactus collection.

Native to the dry regions of Argentina, this cactus thrives in bright light, gritty soil, and a low-water lifestyle. The segments break away easily and root fast, making it both a conversation piece and an easy plant to propagate.

🪴 Bigfoot’s Tip: Don’t panic if segments pop off — that’s just how this cactus travels. Set them on dry soil, and they’ll usually root with time.
