I have tried and have seen occasional roots, If you attatch a bit of stem with the leaf, it will root and form a plant, but grow very slow. I have found the best way to propogate many of them is to start with just a few cuttings, grow em well and big, then chop em down into 2 or 3 inch sections and put into a seedling tray. I like BC hyrdroponics grow plugs for this, they root well in them, especially under a humidity dome. THen I take out the plugs and plant about 30 in a 5"X30" self watering planter. If you want thicker plants, its best to only collect plant apexes to root into the plugs.
