If you can attach steel wire or strong fishing line, and it holds "dirt" with a way for water to drain out, you can hang it up & put plants in it. Window screen &/or landscape fabric can be used as a liner for wire items.
Both steel wire & fishing line are sold in rolls, by length, and rated for the amount of weight it can hold before breaking - for a few $$'s you can hang a LOT of pots. Steel is less frustrating regarding attaching it to things - fishing line is frustrating to tie in a knot but has a cool "invisible" effect that makes pots look like they're floating in the breeze.
And anything that grows down can grow up instead, on a pole or a trellis of any shape/size. Most of them will need your guidance to wind/weave them into a shape or mass of upright-looking foliage. There are flat trellises, tomato cages, poles, and whatever other sturdy structures you can find or make...

basket plant (Callisia fragrans)
More basket plants defying gravity & being forced upward, bracing against each other & widing around the support arms that hang the pot.
This is a little big to bring inside, but I love to put dangly plants in it for summer. Just getting started for the season with, u guessed it, some basket plant. The spiderwort put itself there. Will add more things as time & growth permit. Some Coleus, WJ & ...? :+) I also have an old roundish charcoal grill that is hanging up with steel wire that needs something... Those make great yard pots, already with holes, both the main body & the lid. Fun!
