Golden Ball Cactus

Young plants of Notocactus leninghausii are near-perfect spheres; with age they elongate into short columns and offset at the base to form a low cluster. The whole plant is covered in soft golden bristles that catch the light, which is where the Golden Ball Cactus name comes from.
It is a Brazilian species from rocky grassland, tolerant of more light and less heat than most collectable cacti, and it is as much at home in a bright interior as in a gravel bed.
The Golden Ball Cactus is a container and gravel-bed specimen, valued for the soft gold of its spination rather than for scale.
