Its name derives from Latin and literally means "hairy candle", making reference to its two main characteristics: on one hand, it has the typical candlestick shape of the genus Cereus, with a columnar habit, branched with growth, with deep and marked ribs and sturdy spines; on the other hand, it differs strongly from this genus, due to the thick whitish hair, that covers the entire stem and, when mature, forms a graceful cephalium at the apex. From this down, in summer, showy nocturnal flowers bloom, that will decorate even more this imposing typically glaucous cactus, bringing both a touch of solemnity and elegance to your house.
