I'm a big fan of Platycerium bifurcatum, also known as the staghorn fern. Unlike a lot of ferns, they're not really particular about pH or humidity or soil quality, and they're also somewhat succulent. They CAN be rot prone, I've heard, and they don't really like it if you let them wilt constantly, but watering's not really particularly difficult. I have noticed that young plants are sort of prone to spontaneous collapse. Larger ones are a lot easier for some reason. Also they really benefit from going outside in the summer, and they don't grow constantly. Individual fronds last about three years before falling off. sort of prone to scales. It's not particularly hard to keep scale in check on these, though, because the foliage is really sturdy compared to a lot of ferns. Also the shape of the fronds make it fairly easy to spray them down/scrape if necessary. Also there's lots of cool hanging cacti. Rhipsalis salicornioides is a nice one. You probably want to avoid the spiny ones because I DOUBT you want spiny plants at eye level :) Epiphyllums are one of the coolest things in the world and I'd have one if they didn't get huge.

Probably the easiest are those that do not require any kind of a dormancy [or rest] period. Ones which instead like warm moist conditions all year round. Drosera [sundews]: some good candidates: D. capensis, & D. spathulata lowland Nepenthes: such as N. gracilis, N. ventricosa, N.ampullaria ***be forewarned that pretty much all the neps will at some point outgrow a small terr [15 gal or less] - and most rather quickly [w/in a year or two]. Pinguiculas [butterworts]: ex. P. primaflora Sarracenia [terrestrial pitcher plants] ***same problem as w/ neps Utricularia

Pothos (neon, satin, queens ivy,) -- all fast growers; Monstera obliqua, Philodendron Scandens Micans, miniature Anthurium, (also Caladium humboldtii if you don't mind pulling it for a short rest

A layer of gravel approximately .5-1 inch [1.5 -2.5 centimeters] on the very bottom of the container. Next a 1.5-3 inch layer of 50% perlite and 50% peat has worked well for me. There are other "recipes" out there. For example some people add charcoal to their media. Dried or live sphagnum moss can also be used.
