I grow several green and variegated long stemmed dracaena like this in my greenhouse stream. They LOVE it. I built a 20 foot stream years ago with a small still pool at one end. I threw all sorts of stuff in there...Anubias species, spathiphyllum, arrowhead, and a BUNCH of different dracaenas. They all just took off. Since then, I have thrown rescue plants like dieffenbachia and aglaonema from the Lowes deader rack in barefoot, cuttings of Hoffmania that I accidentally broke, Costus gingers...the main purpose of the stream and the separate pond is to evaporate air and create higher humidity in the winter. Some nearby palms sent out roots that punched holes in the liner years ago, so I keep a hose on steady drip and the water is constantly replenished. Here are a few photos of the stream. All these are growing basically as emersed aquatics
Other that stuff I just toss into the pond or stream, I never root anything in water. Its just not my way LOL
