Identifying Mahonia

We have 2 species of Mahonia in our region– high Oregon grape (M. aquifolia) grows to 8 feet high and dwarf or dull Oregon grape (M. nervosa) grows simply a couple of feet tall. Both are erect stiff branched shrubs with substance leaves that look like holly in leathery look and prickliness. The leaves are a shiny deep green on top and silvery below. Tall Oregon grape has 5-7 leaflets per leaf while dull Oregon grape (it’s anything but dull) has 9-19 leaflets. Both plants have rhizomous roots with a dazzling yellow pigment in the inner bark. Brilliant yellow flowers have 6 petals and are set up in clusters. Properly– Oregon grape is Oregon’s state flower.

Where it Grows: Oregon grapes are northwest perennials that are treasured for their appeal and heartiness. They are typically planted in city landscapes, parks, and along roadsides. Dwarf Oregon grape prefers dubious areas– typically second story Douglas fir forest. It forms a ground cover. Tall Oregon grape chooses sunnier areas in low to middle elevations. It grows in clusters in dry fields and forest margins.

When and How to Harvest: Deep blue berries are generally ripe from July to September. Tall Oregon grape berries are far more respected and grow on stems that are easy to get rid of. I pick them as a cluster then procedure private berries in the house.

As a starting herbalist I was instructed to dig up dwarf Oregon grape rhizomes to harvest the powerful medicinal yellow bark. This was a laborious procedure given that I needed to dig the whole plant, wash the roots, and after that carefully scrape the outer bark with a knife so that all of the yellow bark was gotten rid of from the inner white root. I felt guilty eliminating the plant. Years later, Skokomish Elder Bruce Miller revealed me how to peel the bark off the big stems of tall Oregon grape. He took me to a plant that he had actually been collecting from for over 30 years and it did not look damaged by the taking! I enthusiastically cut a couple of 8-foot stems and easily stripped them– no digging or cleaning required. Out of interest, I checked the berberine material (an alkaloid that has potent medical homes) on both the dwarf Oregon grape root and the tall Oregon grape stem bark with thin layer chromatography. The stem was a little greater in berberine. Needless to say, I have never ever gone back to digging the roots!

Strip the bark with a sharp knife when it is fresh. As it dries it gets surprisingly hard to scrape. If you are digging the rhizomes and roots, wash to eliminate dirt, then strip bigger ones with a knife. Entire smaller roots can be cut with pruning sheers or scissors. Dry in baskets or paper bags. They will last 1-2 years.
