I don't think it actually even needs to root. I have some in my tank - I received it as a very bare and very pathetic stem (maybe 3" length, no leaves) from someone through Craigslist. I left it floating in my tank for a month (basically forgot about it), and then I finally noticed a bronze colored Myriophyllum sp floating around in my tank sometime later with roots that almost had a magenta tinge to it. It ended up being the M. tuberculatum, which I later planted into my substrate.

My tank just has 2 x 24W T5 HO lights over a 20 gal tank with CO2 injection and dosing with Flourish, Iron, Trace, and sometimes potassium and phosphorus. I'm really surprised to hear that you are having difficulty with your plant. I would agree with Tex Gal about the shading though with regard to the M. tuberculatum. If there's not enough light and low iron, it won't turn that nice reddish orange color. See if it improves its condition when you let the stem float on the surface - mine seriously grew from that pathetic stem into a heavily branched one that I easily planted and had to trim back every other week!
