Flying Plants: Island edition

Now I love huge living creatures and fantasy settings, this just might be reflected in my questions, so I had the idea to make a massive living island. I saw a similar question, but unfortunately it asked not how it would work, but how it would evolve and play out, so I still need an answer.

Now to start I said plant, so its flight will have to be passive, so lighter than air gases are needed. My ideas both include giant gas bladders so will that work and how? For my idea the roots would hang down all the way into the ocean, the plant would grow up from the ocean floor. Eventually forming an island which as the bladders are made and start to fill up with the lighter than air gases slowly lifts off. Will this work and if no, how else? PS: For size something massive like the isle of Wight.
