In Short

Native Oregon wildflowers include common camas, Oregon iris, Pacific bleeding heart, western trillium, western columbine, and tall Oregon grape. Most bloom in spring, and April and May are the most abundant months.

More Takeaways
  • All 40 plants check out as native in Kew's Plants of the World Online and the USDA PLANTS database, so none were removed.
  • Oregon law requires written permission from the owner to pick or remove plants on public lands or within 500 feet of a public highway.

Oregon’s Climate and Native Plants

Oregon is located in the Pacific Northwest and provides a varied range of ecosystems. Oregon’s coast occupies warmer zones, while the state’s eastern half experiences colder conditions.

The Columbia River provides wetland habitats and fertile soils. The Oregon high desert in the southeast offers the ideal habitat for desert wildflowers and scrub plants.

How Are Oregon’s Native Flowers Defined?

Oregon's native plants are plants that became established in the landscape without direct or indirect human intervention. Oregon's native plants already occupied the area long before European settlement. This differs from naturalized plants introduced to Oregon’s ecosystems from elsewhere.

How We Checked These 40 Plants

Every plant in this list was checked against Kew's Plants of the World Online and the USDA PLANTS database, state by state, on October 18, 2026. Each entry names the confirming source in a Native Status row, and its scientific name links to its Kew record.

Wrapping Up

Oregon enjoys a charismatic lineup of native wildflowers and flowering plants. These plants occupy a diverse range of habitats throughout the state. Other beautiful native wildflowers include Oregon checker-mallow, diamond clarkia, and Western trillium. Remember that picking native flowers is restricted by place under Oregon law: on public highway rights of way, on public lands, and on other people's land within 500 feet of the center of a public highway, written permission of the owner is required. Oregon State Parks require written permission to pick living vegetation.

Other regional guides cover common British flowers, native Michigan wildflowers, native plants in Arizona, native flowers of Colorado, Ohio native wildflowers, flowers for Texas and North Carolina native flowers.

Questions and Answers

Is it illegal to pick wildflowers in Oregon?

Picking wildflowers in Oregon is restricted by place rather than banned outright. Under ORS 564.020, it is unlawful to cut, dig up, trim, pick, remove, mutilate or injure any plant, flower, shrub, bush, fruit or other vegetation on the right of way of a public highway, on public lands, or on the land of another within 500 feet of the center of a public highway, without the written permit of the owner or the owner's authorized agent. In Oregon State Parks, picking, cutting or removing any living vegetation requires the written permission of the director, manager or designated park employee. A violation of ORS chapter 564 is a Class A violation with a maximum fine of $2,000 for an individual, and the State Department of Agriculture enforces the section.

What is the state flower of Oregon?

The Oregon grape is the state flower of Oregon. The Legislature designated the Oregon Grape (Mahonia aquifolium) as the state flower by resolution in 1899. The Oregon grape is a low-growing plant native to much of the Pacific Coast. It is found sparsely east of the Cascades, and it bears clusters of small yellow flowers in early summer and dark blue berries that ripen in the fall. Kew's accepted name for the plant is Berberis aquifolium, with Mahonia aquifolium as a synonym.

When is the best time to see wildflowers in Oregon?

Spring wildflowers are most abundant in April and May in Oregon. At the Tom McCall Preserve at Rowena, one of Oregon's most impressive displays of spring wildflowers is found from March through June, with the preserve open March 1 to October 31. In Central Oregon sagebrush country, goldfields, sagebrush buttercup, yellow bell, prairie star and spreading phlox are among the first wildflowers of the season, blooming in early spring.

Where are the best places to see wildflowers in Oregon?

The Tom McCall Preserve at Rowena, a plateau above the Columbia River Gorge, is one of Oregon's wildflower displays, with grass widows, prairie stars, shooting stars, balsamroot, lupine and Indian paintbrush growing there, along with four plants unique to the Columbia River Gorge. The preserve is open March 1 to October 31, and visitors should stay on marked trails, leave dogs at home, and avoid weekends in April and May when it is very busy. In Central Oregon, the Deschutes Land Trust lists Whychus Canyon Preserve, Camp Polk Meadow, Indian Ford Meadow and Willow Springs preserves for early-spring flowers including goldfields, sagebrush buttercup, yellow bell, prairie star and spreading phlox.

When should you plant wildflower seeds in Oregon?

For commercial wildflower seed mixes, Oregon State University Extension recommends planting in spring or fall. For spring, seed in mid April in Western Oregon and early May in Central Oregon; for fall, broadcast seed in early November so germination begins in spring. Southern Oregon spring seeding can begin earlier, often late March, while Eastern Oregon is later, often mid to late May, and on the Oregon Coast spring seeding is best delayed until soils are workable and not saturated.
