Same as Godly3vil. If you search my name back from mid 2012 to about the end of 2009 you will see the many plants in my discus tank ( details are in the posts but a few pics are attached here.
The ones I have in with my discus atm are anubias (nana petite, nana and anubias barteri ), 3 or 4 sorts of crypts,magdalensis chain sword, glosso, rotala macaranda, windelov fern and christmas moss.
I don't recall ever having a plant melt due to the extra heat in the tank.
