5-6cm Copiapoa tenebrosa

Copiapoa tenebrosa (Scales of Darkness Cactus) is a striking and distinctive cactus native to the arid coastal regions of Chile. Known for its unique appearance, this species features a deep green to nearly black stem covered in pronounced tubercles and dense, dark spines that create a dramatic, almost architectural texture. The contrast between its dark body and the whitish wool at the crown adds to its mysterious allure.
