My thought is that Dianna's plant was originally two or more planted together in the same pot which is how nurseries/garden centers sometimes grow and sell them. I can see what look to be roots above the soil line on both of those large bulbs which are probably two separate plants that were just potted close together. I'd cut right along the center line between each of them and pot them up separately in shallow pots, using a well draining soil and remember they don't need a lot of water; those bulbous bases store needed water for when the plants need it.
Here's a pot of 5 small Pony Tail's that's been sitting out amidst heavy shrubbery in my yard for the past year ... suffering with powdery mildew from lack of air circulation but you can see where it's different plants all potted together. Maybe I'll try to get up enough energy in the near future and get the bunch out of this pot and separate them.
