Vatisas Bush

Crucial in the production of Mountain Tea, the vatisas bush is a lovely plant that should not thrive in the environment in which it grows.
Really. The bush is scientifically shown to be dependent on such conditions as a moist, warm environment early in its grown cycle, followed by a lot of sunlight and a lot of animals and insects to propagate the seeds. Instead, it grows on the side of a mountain where it will never be warm, in cracks and crannies practically designed to take away the sun, and somehow it still thrives beautifully, contrary to all scientific sense. It must therefore be assumed that some small magic is involved in this species.
It is also entirely possible that Clan Mistbreath, who live on the mountains where this plant typically grows in Deorma, are simply manipulating the environment and not telling anyone.
