The ch'hala tree was a beautiful plant found on Cularin, and was an important part of the religion of the native Tarasin, though they claimed that the trees were not native to Cularin. Harvesting the wood was forbidden by the Cularin Compact of 154 BBY; only trees that died naturally were allowed to be cut down. The roots were crushed to make a fragrant tea. It was found in many Republic gardens on Coruscant, and notably being one of Supreme Chancellor Palpatine's favorite specimens. The tree's bark consisted of a pigmentation that was sensitive to pressure, including sound waves, so the tree would often change in color and pattern in response to noise.
