Spruce Cone Cholla (Tephrocactus articulatus var. diadematus): A Segmented Cactus with Pinecone-Like Stems

Spruce Cone Cholla, or Pine Cone Cactus, has unique, globular to ovoid stem segments that are loosely attached and covered in prominent, spirally arranged tubercles, resembling a pine cone or spruce cone. The segments detach very easily. It has few to no spines, but glochids are present. White to pink flowers appear on new segments. Native to Argentina, it’s a curious, easy-to-propagate cactus for collectors of odd forms.

Taxonomic Profile

Culture

Full sun. Very well-drained, gritty soil. Water sparingly; segments detach if overwatered. Hardy to 20°F (-7°C) if dry. Handle gently—segments fall off easily but root quickly. Great for troughs and rock gardens. Propagate by laying segments on soil.
