Determining Mahonia

We have two species of Mahonia in our region– tall Oregon grape (M. aquifolia) grows to 8 feet high and dwarf or dull Oregon grape (M. nervosa) grows just a few feet high. Both are erect stiff branched shrubs with compound leaves that look like holly in leathery appearance and prickliness. The leaves are a shiny deep green on top and silvery below. Tall Oregon grape has 5-7 brochures per leaf while dull Oregon grape (it’s anything however dull) has 9-19 leaflets. Both plants have rhizomous roots with a fantastic yellow pigment in the inner bark. Bright yellow flowers have 6 petals and are arranged 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 frequently planted in city landscapes, parks, and along roadsides. Dwarf Oregon grape chooses dubious locations– often 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 usually ripe from July to September. Tall Oregon grape berries are much more respected and grow on stems that are easy to get rid of. I pick them as a cluster then process individual berries in the house.

As a beginning herbalist I was instructed to collect dwarf Oregon grape rhizomes to harvest the powerful medical yellow bark. This was a tedious procedure considering that I needed to dig the entire plant, wash the roots, and then carefully scrape the outer bark with a knife so that all of the yellow bark was removed from the inner white root. I felt guilty killing the plant. Years later on, Skokomish Elder Bruce Miller revealed me how to peel the bark off the large stems of high Oregon grape. He took me to a plant that he had been collecting from for over 30 years and it did not look damaged by the taking! I enthusiastically cut a few 8-foot stems and quickly removed them– no digging or cleaning needed. Out of curiosity, I checked the berberine material (an alkaloid that has potent medicinal 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 greater in berberine. Needless to say, I have actually 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. Whole smaller sized roots can be cut with pruning sheers or scissors. Dry in baskets or paper bags. They will last 1-2 years.

  • As soon as ended up, measure your juice/pulp. It must yield about 3 cups. If you have less you can include a little water to bring your volume to 3 cups.
  • Place a pot on the stovetop, add the juice, 1 ounce of pectin (about 1/2 of a liquid bundle) and the juice of 1/2 lemon. Stir well and then turn onto high heat, stirring consistently.

Mahonia/Oregon Grape Lavender Jelly (Low sugar)

I tried this dish for the first time this year and I like it much better than the high sugar jelly. I used Pomona’s Universal Pectin.

Since it stimulates gastrointestinal juices, it also acts as a laxative.

Oregon grape promotes liver function.

Lots of Americans have a pattern of liver deficiency. The liver is accountable for many functions consisting of:.

  • Breaking down metabolites and contaminants.
  • Producing bile, which assists break down fats and proteins, and serves as a laxative.
