Palm is actually a grass and is probably the first plant domesticated by man. The hard ribs of the fronds are used to make boxes, the leafy part of the frond is used for mats, baskets and the like. The brown fiber that covers the base of the frond makes some of the strongest rope I've ever used, though pretty scratchy, and is formed into brooms and other cleaning implements. The wood is quite soft and porous but in our dry climate can be used for some building purposes. Unprepared, the logs are often used for informal bridges across canals or for walls. The prepared logs are often used in house construction.
