I know what you mean.
I am doing alright with it, but it just doesnt make any roots at the
bottom.
I usually bury it in the gravel to hold, but it either rots or the fish
suck too much on it, and I have it flooting in the water. 
I really want that plant to develop, it is beautiful.
I have a 10 gallon quarantine tank with no gravel. I have found some
plants do ok weighted and no gravel. A couple of times I moved the
plants to a 29 gallon community tank while I had medicine in the
quarantine tank. Again I let them float on the bottom only to find
some planted themselves, the roots just extended from the bottom stems
into the gravel.
As to your pet plant, I have no specific knowledge. How about
planting half of what you have and floating the other half and see
what happens.
Perhaps someone will have direct experience, so much nicer than making
guesses.
