I poorly described the growth of the plant. Each leaf grows on a rather long 
stem, sometimes 4 inches or greater. With the actual leaf growth beginning 
sometimes midway up the tank, I have 15-20 inch leafs growing up and laying 
on top of the water in bunches--which I am forced to keep removing because it 
blocks light to other plants. It's also located near a powerhead which 
doesn't help matters. Each leaf is wide and undulating, but perhaps because 
it is growing near enough to the light because of the elongated stems? I'd 
guess I'd say this is healthy growth, and it's producing flower stalks every 
few weeks or so. Just doesn't seem to show well in my tank, I guess.

Thanks for the replies.
