It depends on what you plan to do with it and what kind of conditions you are going to grow it in. When you asked this question duckweed/pondweed comes to mind, but if you want a more structured plant I would say I've had the most luck with my Amazon swords - but then you probably need a tall tank and a bit higher light than the norm - so what are your conditions? I'm sure someone else could tell you what you're looking for if they knew your tank specs and preferences for growth habit, etc.
I'd say Java Fern is the easiest plant I've grown. It grows pretty slow, but I just let it float all around my tank. It seems to go wherever it wants anyways.

Seconded. Tie several bunches of JFern to a piece of driftwood, place it under the lights, and let it go. JFern has grown in every tank of mine, except for one that's just under 1WPG (only crypts are doing well in that one).
java moss, period. i didnt want mine anymore so i put it in a jar by the window, no special light and the water must have been like 40 degrees. its still alive.
Java fern and Anubias are quite easy. Low light and not picky at all.
I've had a lot of luck with Amazon swords as well, even though my light is only 1.5 WPG in a 10 gallon aquarium. They've been thriving for more than 2 years.
OMG yall are forgetting (IMO) the most invasive aquatic plant of all !! CAMBOBA !! don't use this plant in any circumstance it's as bad or worse than duckweed! It roots like mad & spreads like wildfire & clogs inlets with it's needles.Never flush this stuff .Ive found it in every waterway Ive ever seen.
