I bought these at Home Depot in May. They were potted together, so I perpetuated that problem by planting them together in a 6-inch pot.

Another view -

Now they have grown and are showing some winter color.

And a view of both -

Initially, I thought the leaves were more paddle shaped, but they have grown to be pointy. They already need repotted as roots are coming out of the bottom. I think I really misjudged the size this plant will get.

I thought this was probably Aloe martholii or perhaps Aloe ferox. Am I on the right track, or should I look in a different direction? Surely, they will not be happy in a 6-inch pot!

Thanks for your help!
