The Gymnocalycium horstii, commonly referred to as Ball Cactus, has a globose shaped stem with minimal spines, only growing a little under a foot tall. The plant can be easily propagated by removing pups at the base of the stem or you can let them clump freely to produce a more interesting specimen. Like other cacti, this drought-tolerant species will pair well in any room with a sunny window!
Each plant is unique; size and shape fluctuate by season so all measurements are shown as a range
Small plants measure 2-4" tall from the soil line to the top of the foliage
