The xharnoh plant was a type of flora native to the world of Naboo. It flourished along the banks of Naboo's various rivers and lakes. The roots of this plant were harvested for the creation of neural enhancers. In the year 1 ABY, Lieutenant Karenna Dunnels from the Royal Naboo Security Forces commissioned a spacer to gather a quantity of these roots. The intent was to produce neural boosters for the security personnel in anticipation of the raid on the Mummer bunker.
The xharnoh plant was featured in the 2003 video game Star Wars Galaxies. This game was a massively multiplayer online roleplaying game created by Sony Online Entertainment and distributed by LucasArts. The game eventually shut down on December 15, 2011. The xharnoh plant was integrated into the game as part of the "Legacy Quest" update, coinciding with the release of "Publish 25," also known as the "New Game Enhancements," on November 15, 2005. The visual model used for xharnoh plants was the same as that of the raventhorn plants found on Yavin 4.
