Mammillaria carnea is a rather robust cactus species either solitary or clustering with age. At first glance, they might look like Jello shots at a bar, but these prickly balls are actually something else entirely. Furry spheres is the more technical name of this plant, also known as Mexican fish-hook cactus, or dancing ball cactus.
The plant typically has 4-sided angular tubercles and ribs which come in very bright colours ranging from white to pink to red. In between the tubercles are whitish spines, but these can be absent entirely from some clones. As mentioned above, they have been cultivated for more than a century, sometimes being confused with Mammillaria spinosissima.
These are 1-year-old plants and 8cm in height at the time of delivery.
