Devil's club
Devil's club or devil's walking stick (''Oplopanax horridus'', Araliaceae; syn. ''Echinopanax horridus'', ''Fatsia horrida'') is a large understory shrub endemic to the arboreal rainforests of the pacific northwest, but also disjunct on islands in Lake Superior. It is noted for its large palmate leaves and erect, woody stems covered in noxious and irritating spines. It is also known as Alaskan ginseng and similar names, however it is not a true Ginseng.
== Description ==
Devil's club generally grows to tall; however, instances exist of it reaching in excess of in rainforest gullies. The spines are found along the upper and lower surfaces of veins of its leaves as well as the stems. The leaves are spirally arranged on the stems, simple, palmately lobed with 5-13 lobes, across. The flowers are produced in dense umbels diameter, each flower small, with five greenish-white petals. The fruit is a small red drupe diameter.〔
The plant is covered with brittle yellow spines that break off easily if the plants are handled or disturbed, and the entire plant has been described as having a "primordial" appearance. Devil's club is very sensitive to human impact and does not reproduce quickly. The
plants are slow growing and take many years to reach seed bearing maturity, and predominately exist in dense, moist, old growth conifer forests in the Pacific Northwest.〔
