Recognizing Mahonia

We have 2 species of Mahonia in our region– tall Oregon grape (M. aquifolia) grows to 8 feet tall and dwarf or dull Oregon grape (M. nervosa) grows simply a few feet tall. Both are erect stiff branched shrubs with substance leaves that look like holly in tough appearance and prickliness. The leaves are a shiny deep green on the top and silvery underneath. Tall Oregon grape has 5-7 brochures per leaf while dull Oregon grape (it’s anything but dull) has 9-19 brochures. Both plants have rhizomous roots with a brilliant yellow pigment in the inner bark. Bright 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 valued for their beauty and robustness. They are commonly planted in city landscapes, parks, and along roadsides. Dwarf Oregon grape prefers shady areas– often 2nd 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 typically ripe from July to September. Tall Oregon grape berries are a lot more prolific and grow on stems that are simple to remove. I choose them as a cluster then procedure individual berries in your home.

As a starting herbalist I was instructed to collect dwarf Oregon grape roots to gather the powerful medicinal yellow bark. This was a tedious process because I needed to dig the entire plant, clean the roots, and then thoroughly scrape the external bark with a knife so that all of the yellow bark was gotten rid of from the inner white root. I felt guilty killing the plant. Years later on, Skokomish Senior citizen Bruce Miller showed 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 gathering from for over thirty years and it did not look harmed by the taking! I enthusiastically cut a couple of 8-foot stems and quickly stripped them– no digging or cleaning necessary. Out of interest, I checked the berberine content (an alkaloid that has powerful medical residential or commercial properties) on both the dwarf Oregon grape root and the tall Oregon grape stem bark with thin layer chromatography. The stem was a little higher in berberine. Needless to say, I have never ever returned 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 get rid of 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.

Numerous Americans have a pattern of liver shortage. The liver is accountable for numerous functions including:.
