Agreeing with both Carol and Nate! Annadvn, I have 3 different swords in my 30g long (w/
UGF) and one, Echinodorus bleheri I believe, is doing just this. For the last 8-10 weeks it has been sending longer stemmed leaves right up out of the water. I have taken the glass off to let them fully emerse. You can see some in the center of the tank, brhind the Banana plant that has also sent "pads" up.

As far as transplanting any plant grown submersed to an emersed environment, (if thats what you were asking?) I don't have any experience. But have fun with the plants, we all agree they are rewarding!
