Cubical Cactus

This cube-shaped cactus has been on my wishlist for years! I was thrilled to see it for sale at The name is a mouthful: Astrophytum myriostigma var. quadricostatum. The typical form of A. myriostigma has 5 ribs, but this variation has only 4 (at least for now; over time it’s likely that it may grow more). I’m thoroughly enjoying the unusual shape and the bright yellow blossoms perched on top!
