I would advise against putting spider plants in the ground at all unless you have a very large area for them to take over. The arching stems of baby plants will lean to the ground, the babies take root, and the whole patch becomes a tripping hazard (and good place for snakes to hide) if you try to walk through to pull weeds (or for any reason.)
In a pot, I think the plants would need to occupy the same air-space, so I do not know how good they would look together.
This unruly patch formed in just a couple years from putting about 5 very small babies in the ground.
The *VERY* big and deep roots of C. comosum plants make them very difficult to dig up once they get established in the ground.
