Devil's Club (syn. Echinopanax horridus, Fatsia horrida) is a large understory shrub endemic to the arboreal rainforests of the pacific northwest, and is most abundant in old growth conifer forests. It is noted for its large palmate leaves and erect, woody stems covered in noxious and irritating spines. Devil's Club generally grows to 1 to 1.5 metres (3 ft 3 in to 4 ft 11 in) tall. Some stands located in rainforest gullies or moist, undisturbed areas can reach heights of 3 metres (9.8 ft) to 5 metres (16 ft) or more. It is also known as Alaskan Ginseng.
