Oregon Grape was adopted in 1899 by Senate Concurrent Resolution Number Four of the Oregon Legislative Assembly, the State of Oregon on January 30-31, 1899 as Oregon official state flower.
A low growing plant, the Oregon Grape, (Berberis aquifolium,) is native to much of the Pacific Coast and found sparsely east of the Cascades.
Its year-round foliage of pinnated, waxy green leaves resembles holly. The plant bears dainty yellow flowers in early summer and a dark blue berry that ripens late in the fall. The fruit can be used in cooking. Oregon grape is a close relative of barberry (Berberis vulgaris), and as with its cousin, the plant's medicinal portion is the root. Although Oregon grape originated in North America, it now also grows in Europe.
Oregon grape is a low-growing shrub from 2 to 5 feet in height, resembling the holly of the Eastern States. The leaves are divided like those of an ash; the five to nine leaflets from 2 to 3 inches long and about 1 inch wide are evergreen, thick, leathery, smooth, and shining on the upper surface with marginal spines. The numerous small yellow flowers appear in April and May and are borne in erect clusters. The fruit consists of a cluster of blue berries. The rootstock and roots are more or less knotty, about an inch or less in diameter, with tough yellow wood and brownish bark.
The law designating the Oregon grape as the official Oregon state flower is found in the Oregon Revised Statutes, Title 19, Chapter 186. Senate Concurrent Resolution No. 4 is cross-referenced in chapter 186.
TITLE 19. MISCELLANEOUS MATTERS RELATED TO GOVERNMENT AND PUBLIC AFFAIRS.
