Like Rotala rotundifolia, it is a stem plant with narrow, lanceolate leaves, but its leaves are longer and are lighter green. Its many leafed crowns further distinguish it from elodea and Rotala rotundifolia. It looks especially star-like when individual stems are planted at different heights. Stargrass requires a pH of 6.0-7.5, a carbonate hardness of 3-15 degrees, and bright light in order to grow well. Stargrass is very versatile in that it can be used as a foreground, mid-ground and background plant. The reason for this is that it can be trimmed and shaped just like a hedge. When used in the foreground it should be trimmed to about an inch or so; side shoots will develop below the cutting point and soon you will have a rich, green carpet. In mid-ground stargrass can be used to butt up against other plants, concealing the bottoms of those stem plants with scant leaves. Left to its own devices, it will grow about 20 in. tall, making it suitable for the back and sides.
