I've accidentally rooted Butterfly Bush starts in my tank. Had them sitting in the tank until I could use them for an art project, and lo and behold, I accidentally some trees.
Coleus roots crazy fast in tank (3 days), same with prayer plant. I'm rooting a Rose of Sharon in a (non-planted) vase, and it's started growing roots within a week. In a tank, with lots of oxygen and circulating water, I'm guessing it'd root even faster. Pretty much anything you can root in water can adapt to riparium life
The only reason I can't keep most plants in a riparium setting is because they grow too fast and get too big!
