Ch'hala tree

The ch'hala tree was a beautiful plant found in the many Republic gardens on Coruscant, and notably one of Supreme Chancellor Palpatine's favourite specimens. The tree's bark consisted of a pigmentation that was sensitive to sound, so the tree would often change in color and pattern in response to noise.

Palpatine awarded Jedi Master Shaak Ti a grove of ch'hala trees, in recognition of honorable deeds in protection of the Republic. Shaak Ti donated the grove to the Jedi Temple, where it was set up in a prominent location for all Jedi to appreciate.

During the reign of the Empire, Palpatine set up a number of these trees throughout the Imperial Palace.

These trees all over Coruscant became an integral component of a sophisticated spy system - codenamed Delta Source - that Palpatine used to monitor his courtiers and officers.

Many years later, Grand Admiral Thrawn used these same system of trees to gather vital information about the New Republic's military campaigns.
