Closely resembling the mighty Saguaro, it grows multiple arms out of the primary stem, blooming large white flowers out of the top of the structure during summer months. Not only is this a beautiful cactus. It’s also extremely fast-growing when given proper care and attention. It starts off as a fat columnar cactus. Younger species are smaller but after many years, this species will grow bigger and taller, and produce its characteristic side arms. Whether in natural surroundings or in a garden, the Cardon Grande is capable of reaching 10 to 15 meters tall with a diameter of 60 centimeters. Cardon Grande also produces large white flowers. These flowers can reach lengths of 15 to 22 centimeters, and widths of 14 centimeters. Each petal can be as long as 8 centimeters. The flowers have tubes with brown, woolly hair.
