Ensete glaucum is an herbaceous plant that can reach heights of up to 5 meters and does not form runners. It contains a pale yellow-orange milky juice . Their pseudo-trunk , thickened at the base, is cylindrical and yellow-green in color, with black-purple spots when old. The short-stalked leaves are 1.4 to 1.8 meters long and 50 to 60 centimeters wide, the blade is oblong, round, glabrous, wedge-shaped at the base and tailed at the very end.
The inflorescence is up to 2.5 meters long, the shaft cylindrical. The numerous bracts stand on top of each other like roof tiles and are permanent, with ten to twenty flowers per bract . The overgrown bracts measure 2.5 centimeters and are triple slit at the extreme end, the shorter free bracts are inverted heart-shaped and have a mucro at their extreme end .
The fruits are bare, black-violet berries that are up to 9 inches long and 3.5 inches thick. They are obovate to oblong-round, pointed at the base and rounded at the extreme end with a persistent perianth . The smooth, black, spherical seed measures about 1.2 cm in diameter.
