Fall Foraging in Portland: September

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.
