It grows to a height of 15 meters, with a stout trunk. Its distinctly bluish leaves are 1-2 meters wide, with meter-long petioles. The leaves are persistent in nature, forming a shag around the trunk; in cultivation they are typically burned or cut off. The inflorescences extend out beyond the crown, reaching 5 meters in length. The flowers themselves are small, appearing in February and March, while the fruits are 18-24 mm in length, brown and with a generally ovoid to globose shape.
