Justin at Ocean Aquarium in San Francisco uses superglue to secure java fern and anubias to wood and rocks. The advantage is no tying, no threads to look at, and the superglue adheres even when the plant and wood are damp. The stuff is toxic though, but he hasn't seen any problems because of it.

Corals are superglued to live rock in reef aquariums, there are no toxicity issues.
