It gets the fond common name from its equally wide and tall growth habit that give it an overall tomato-shaped appearance. It’s spines curve inward and with enough light and proper care, produces beautiful light pink flowers.

Like most cacti, they are slow growing and prefer bright, direct sunlight (6+ hours daily) and watering only when soil is completely dry. Pot in a well-draining cactus/succulent soil mix. Avoid watering in the winter months, and allow to rest/go dormant.
