What Is the Oregon State Flower?

Oregon recognizes the Oregon Grape as its state flower. Bright yellow flowers bloom in dense clusters. Each cluster contains 25 to 75 individual flowers. The blooms measure about a quarter inch across. A sweet fragrance attracts early spring pollinators. Shiny evergreen leaves resemble holly with spiny edges.

Oregon Grape blooms from March through May across the state. Peak flowering occurs in April in most regions. Coastal areas see earlier blooms than mountain elevations. The shrub grows 3 to 6 feet tall in typical conditions. Some specimens reach 10 feet in ideal locations. Dark blue berries ripen in late summer resembling small grapes. The berries have a waxy coating.

This native shrub grows wild throughout Oregon forests from the Coast Range to the Cascade Mountains. The plant thrives in partial shade under Douglas fir and oak canopies. Well-drained acidic soil suits Oregon Grape best. The species appears in the Columbia River Gorge, Willamette Valley, and throughout western Oregon lowlands. Eastern Oregon's drier regions support the shrub in protected canyons. The evergreen foliage provides year-round habitat for birds and small mammals, especially in forests tied to the Douglas Fir state tree.

Oregon State Flower Name

This plant carries the common name Oregon Grape and the scientific name Mahonia aquifolium. The species belongs to the Berberidaceae family. This family includes barberries and about 700 species of shrubs found worldwide.

The genus name Mahonia honors Irish-American horticulturist Bernard McMahon. The species name aquifolium means holly-leaved in Latin. It describes the spiny evergreen leaves. Common names include tall Oregon grape and holly-leaved barberry. The name Oregon grape confuses some people since the plant is not a true grape.

The berries look like small grapes but taste quite tart. Native Americans harvested the berries for food and medicine. They used the yellow roots to make dye. Lewis and Clark documented Oregon Grape during their expedition. David Douglas collected specimens for European botanical gardens in the 1820s. The plant became popular in England before Oregonians recognized its value.

How Oregon Chose the Oregon Grape

Oregon made the Oregon Grape its official state flower in 1899. This designation came only 40 years after Oregon achieved statehood. The legislature acted without organizing a formal public vote. The plant's name already connected it strongly to Oregon in people's minds and to what became the Beaver State identity.

Oregon Grape grew abundantly in forests throughout western Oregon. Settlers found the yellow flowers brightening spring woodlands. The evergreen leaves provided winter color. The berries fed wildlife and could be eaten by humans. The plant served medicinal purposes for Native Americans and pioneers.

Some people suggested roses or wild rhododendrons instead. Oregon Grape supporters argued no plant bore Oregon's name more prominently. The shrub grew naturally only in the Pacific Northwest. Its widespread distribution throughout Oregon made it representative. The legislature agreed. Lawmakers passed the designation on February 13, 1899. Oregon became one of the earliest states to adopt an official floral emblem.
