They created real ornamental weaves with this foliage, to create one of the most used tools within the tribe. In the West it is imported and used above all to create the famous architectural and spectacular gardens that have depopulated in the West for years. Today this long-leaved plant is mainly used in parks and gardens to create that neutral “carpet” on which to place one’s most precious flowers.
