It reproduces by seed, in organic loam maintained constantly humid at the temperature of 24-26 °C, but usually and easily by division.

Species with ornamental foliage little known out of its origin zones, cultivable in the tropical and humid subtropical climate regions in partially shaded position and without particular necessities concerning the soil, even if poor, but with ample and constant water availability. The leaves are locally utilized as cover of rural dwellings and to wrap and cook food on the grill; the fibres gotten from the stems are used to realize mats, baskets, fishing nets and common usage articles.
