With the blue-green cylindrical stem and entirely covered with intertwined thorns, this small solitary cactus will surprise you in spring or early summer with its beautiful yellow flowers up to 6 cm in size. They will open gently with the first lights of the morning as if to wish you good morning and then close at sunset . The name “tabularis” comes from latin and means "flattened, like a plate", referring to the flattened globular body shape.
