The plants are large herbs and bear very large leaves and the lower parts of the leaves form a false stem which make them look like trees in appearance. They do not appear very tall and are perennial herbaceous plants. The lower part of the leaves encloses a false stem also known as pseudostem which is not made of wood. However, the true stem grows underground and is called the rhizome. The flowers bear bracts and grow in groups or inflorescences flowering occurs.
