Although it is commonly called Oregon grape, or alternately barberry or holly grape, Berberis repens is neither a grape nor is it confined to Oregon. It does have pretty yellow blossoms, though, that are attractive to honey bees and bumblebees. The berries can be made into an excellent jam and this plant has medicinal properties.
It shouldn’t be consumed by pregnant or lactating women, though.
It does look like holly. Great info. I havent seen this.
In many of these, the leaves also have spines like holly. Most are low-growing, though, and the berries are normally deep purple when they are ripe.
