OREGON GRAPE
Oregon's state flower blooms on this attractive, fast-growing shrub, which is popular in ornamental landscaping. Oregon grape has shiny dark green leaves, resembling holly leaves in their shape, color, and spininess. The plant's flowers are small and yellow-green. They are followed by the berries, which turn dark purple-blue when they are ripe. The clusters of berries resemble small bunches of grapes, and they are edible. The shrub can reach 6 feet in height, but it usually grows about 3 to 4 feet tall. Oregon grape prefers a shady location and a fairly rich, well-drained soil (although we have seen it do well when cultivated in full sun and rather heavy soil). Its natural range is from Colorado west to northern California, then north to Canada. You can propagate oregon grape from cuttings taken in midsummer. The new plants will be ready to set out the following spring. Oregon grape can be grown from seed, too. Collect seeds from the berries in the fall, and plant them outdoors so that stratification (exposure to cold temperatures) occurs. Plants can also be obtained at many landscaping nurseries. The root is the part of the oregon grape that is most often used for healing purposes. Do not gather it before the second year of the plant's growth, in late autumn, or in climates where the ground does not freeze during the winter. After harvesting the roots, you can replant the root crowns, and they will sometimes produce new plants. Some herbalists suggest digging up the earth around the roots, and making the harvest by pruning away one-fourth to one-third of the roots with shears, leaving enough of the root system for the plant to survive. Oregon grape is ranked by some herbalists among the most outstanding native American herbs. Its bright yellow root is high in the alkaloid berberine, which is a constituent of other powerfully healing plants such as goldenseal. Many American herbalists believe that oregon grape stimulates liver activity and the secretion of bile.

Modern herbalists use oregon grape to cleanse the spleen, as well as the liver and blood.
