It is a rare, slow-growing succulent plant with a green, globular stem that tends to stretch up and cluster. Unlike D. longimamma, this cultivar has much more compact tubercles and very sparse and short spines. It's a bizarre cactus that resembles an artichoke and is highly sought after by cactus collectors for its unusual shape. While growing D. longimamma f. monster stretches up and tends to lignify at the base. Its yellow flowers open up during the day.
