15 Wildflowers in Oregon

The state wildflower of Oregon

The state wildflower of Oregon is the Oregon Grape, also known as Mahonia aquifolium. This evergreen shrub is native to the Pacific Northwest region of the United States and is commonly found in the forests and mountains of Oregon.

The Oregon Grape is known for its beautiful yellow flowers, which bloom in early spring and are followed by clusters of blue-black berries in the summer.

In addition to its aesthetic appeal, the Oregon Grape has also been used for medicinal purposes by Native American tribes for centuries, and is still used today in herbal medicine.

In 1899, the Oregon Grape was officially designated as the state flower of Oregon, and it remains a beloved symbol of the state’s natural beauty and rich cultural heritage.

Let’s learn more about the Oregon grape and some of the state’s other wildflowers.
