In season now
Pacific Crabapple
Where: Hedgerows, open woodlands, and disturbed areas throughout the metro area and surrounding foothills.
Small hard apples (2–4 cm) ripen to yellow or red in late August through September; tart and astringent raw, excellent for jelly, cider, or pectin. Pick when fully colored and slightly soft to touch.
Look-alikes: Ornamental crabapples in yards are edible but may have been sprayed; wild Pacific crabapples are smaller and grow in natural settings.
Oregon Grape (Mahonia aquifolium)
Where: Understory of mixed conifer and oak woodlands, especially east of Portland in the foothills; common in native plantings.
Waxy blue-black berries in tight clusters ripen September–October; tart and astringent, used for jelly, syrup, or dried. Harvest when fully dark and dusted with white bloom.
Look-alikes: No dangerous look-alikes; other Mahonia species (tall Oregon grape) are also edible but less common locally.
Blackcap Raspberry (Rubus leucodermis)
Where: Forest edges, clearings, roadsides, and disturbed ground throughout the Willamette Valley and foothills.
Dark purple to black berries (smaller than red raspberries) ripen August through September; sweet and mild. Pick when fully dark and easily detached.
Look-alikes: Red raspberries are edible; black raspberries are not toxic but blackcaps are distinct and preferred for flavor.
Miner's Lettuce (Claytonia perfoliata)
Where: Moist shaded areas, stream banks, and disturbed ground in woodlands and gardens.
Tender round leaves with a central hole; mild, slightly succulent flavor. Harvest young leaves before flowering (late September onward); use raw in salads or lightly cooked.
Look-alikes: No dangerous look-alikes; distinctive round perfoliate leaves are unmistakable.
Stinging Nettle (Urtica dioica)
Where: Disturbed ground, stream margins, and rich soils throughout Portland and surrounding areas.
Young tender tops (top 10–15 cm) are edible when cooked; rich in minerals and vitamins. Harvest with gloves before flowering; cooking destroys the sting.
Look-alikes: Dead-nettle (Lamium) is harmless and lacks the sting; nettles have opposite leaves and square stems.
Hazelnut (Corylus cornuta ssp. californica)
Where: Understory of mixed woodlands, especially in the foothills east and south of Portland.
Small hard-shelled nuts in a bristly husk ripen September–October; sweet kernel inside. Crack shell and eat raw or roasted; harvest when husk turns brown.
Look-alikes: No dangerous look-alikes; distinctive bristly husk is diagnostic.
Coming soon
Acorns (Oregon White Oak, Garry Oak)
Acorns mature October–November; must be leached of tannins before eating. Abundant in oak woodlands east of Portland.
Mushrooms (Chanterelle, Hedgehog, Puffball)
Prime season begins mid-September after rain; requires expert ID. Consult local mycological society before harvesting.
Arbutus Berries (Arbutus menziesii)
Small orange berries ripen October–November on the distinctive peeling-bark madrone tree; mealy texture, marginal flavor.
Safety in this area
- Poison oak (Toxicodendron pubescens) is common in dry oak woodlands east of Portland; three leaflets, reddish in fall, causes severe skin reaction—learn to ID and avoid.
- Ticks are active in tall grass and brush, especially in foothills; check skin after foraging and remove promptly with tweezers.
- Giant hogweed is present in scattered locations in the Willamette Valley; causes severe phytophotodermatitis (blistering on sun-exposed skin)—never touch; report sightings to ODA.
- Always forage on public land or with explicit permission; much of the Portland metro area is private property or protected habitat.
Foraging information is educational. Confirm every identification with a regional field guide or expert before eating anything wild.
