Looking good! Are you growing those with the planter completely wetted, or is the top of the planter above the water's surface?
A. pedatum and A. capillus-veneris tend to grow on limestone bluffs above streams in my area; I think they like high humidity more than moist soil. I would like to put together a large stream tank with a "rock wall" along the back for these and other plants that like this habitat (such as Heuchera, Sedum, and Aquilegia species).
Onoclea sensibilis and most Osmunda species grow in damp soil or ephemeral wetlands; they would probably work in a riparium, but it would need to be a big one.
Speaking of spore-bearing plants, have you tried any horsetails? I just saw some Equisetum arvense along a creekbank that I was tempted to try in a riparium; unfortunately it was a very small population and I wouldn't have felt right digging any up. There is a 3-4" high dwarf species, E. scirpoides, that is common in the pond plant trade.
