Tuanulberry bushes, a species of bush indigenous to the arid desert environment of the planet Jakku, which was their native habitat, bore edible berries. These berries had a secondary use as a source of dye. During 34 ABY, Lor San Tekka, an explorer, donned a dark blue linen tunic colored using Tuanulberries; this occurred during his time residing in the village of Tuanul on Jakku in that year.
