You can grow a lot of aquarium plants emersed as long as the humidity stays high. However, with time some plants can be transitioned over to a less humid environment.
Currently I am growing anubias, crypts, java fern, java moss, HC, glosso and pennywort emersed quite successfully. Don't do anything special, just Miracle Gro potting mix under sand and a light over the top for 6 or so hours a day.
My anubias just sent off a new leaf, crypts have been shooting like crazy and my java fern has also unfurled a couple of new leaves as well.
Just putting this out there as another possibility.
