Oregon to Keweenaw
Making tea might not be the only reason to include Oregon tea tree in Indian commerce. These flowers make a good green dye. The entire plant, beaten in water, makes an effective if mild soap. Use it for a wash that doesn't remove skin oils. This shrub also had a variety of medicinal uses. But of course there is also another possibilty for this disjunct distribution. The fruits are eaten by wildlife, and the bush is grazed by herbivores. Certainly birds could account for this range fragmentation.
