A plant found naturally on Vulcan, common across much of its cooler lowland regions. G’teth is a bush which grows on the shady side of desert and semi-desert hills, and is cultivated by farmers. G’teth plants serve as windbreaks for other crops, and help prevent erosion. The berries of the g’teth are also useful; they take the form of small, brownish-green buds which can be crushed and used to make a beverage, the justly-famous Vulcan mocha.

G’teth plants are cultivated in gardens, including that of T’Les in the 2150s. Following her death, Denak tended it while caring for the grounds. During a visit by T’Pol in 2155, he told her she might find new fruiting on the g’teth.
