[Wikipedia] Uses: Like other manzanitas, this species has a hard, attractive wood that has proved useful for making tools and as firewood. The fruit is edible and has a pleasant tartness, but the seeds cause gastrointestinal upset if eaten in large quantities. It has historically been brewed into a cider, including by Native Americans.[1] They are also consumed by bears and chipmunks.[2] (link added by Mary Ann Machi)
