Rattan is a type of climbing palm that is very long with a slender stem which maintains an almost uniform diameter throughout its length. It grows in a manner similar to a vine, but has an inner core and is not hollow like bamboo. The outer portion of the stem is extremely hard and durable, while the inner portion of the stem is softer and porous. The shade in the rain forests is very dense and climbing on tree limbs is the most practical way for the rattan vines to reach the light above the forest canopy. This makes Rattan ideal for continuous strips of reed and it is considered to be one of the strongest woods available ideal for weaving.
