Description

The stems are straight and erect, the inferior part is covered with “vainas” from the fallen leaves, while in the superior part the leaves are arranged in fan shaped groups.

There are many varieties in the plant's stems. The bark zone, which is the main factor in the unusual height, functions as a water distribution system, transporting water from the underground roots to the superior part of the plant including the leaves. This vital function occurs throughout each season of the year.

Uses

*In Colombia is used to create different accessories including the traditional sombrero vueltiao, symbol of Colombia.
