In season now
Blackcap Raspberry
Where: Disturbed areas, forest edges, roadsides throughout King County
Black berries, firm and slightly tart; pick when fully dark and they release easily from the core. Excellent fresh or for jam.
Look-alikes: Black raspberry closely resembles blackberry (Rubus species), but black raspberries have a hollow core when picked, while blackberries retain the core.
Caution: Watch for thorns; wear long sleeves.
Pacific Crabapple
Where: Native to Puget Sound region; found in open woodlands, stream margins, and old homestead sites
Small, hard, tart yellow or red apples; harvest when they begin to drop naturally. Use for jelly, cider, or pectin source.
Look-alikes: Ornamental crabapples in gardens may be treated with pesticides; forage only wild trees away from developed areas.
Caution: Ensure trees are on public land or you have permission; seeds contain cyanogenic compounds, so discard them.
Miner's Lettuce
Where: Moist shaded areas, stream banks, disturbed ground in lowland forests
Round leaves with a hole in the center; mild, tender greens ready to eat raw in salads or lightly cooked. Peak now before frost.
Look-alikes: Chickweed (Stellaria media) has opposite leaves without the central hole and is edible but less tender.
Caution: Confirm ID before eating; rinse thoroughly to remove soil and potential parasites.
Stinging Nettle
Where: Disturbed, nitrogen-rich sites near water, forest margins, and old gardens
Opposite leaves with serrated edges and fine hairs; harvest young tops (top 10 cm / 4 inches) with gloves. Boil or steam to remove sting; excellent nutritious green.
Look-alikes: Dead nettle (Lamium) lacks stinging hairs and has a different leaf shape; both are edible but dead nettle is milder.
Caution: Wear gloves when harvesting; cook before eating to neutralize formic acid in the hairs.
Salal
Where: Understory of Douglas fir and western hemlock forests, common throughout Puget Sound lowlands
Dark purple-black berries with a waxy bloom; sweet and mild, eaten fresh or dried. Peak harvest mid-September through October.
Look-alikes: Huckleberries (Vaccinium species) are similar but smaller and grow on different shrubs; both are edible.
Caution: None; salal is safe and abundant.
Wood Sorrel
Where: Shaded gardens, forest floors, disturbed areas with moist soil
Clover-like leaves with a lemony, tart flavor; eat raw in small quantities as a salad accent or tea. High in oxalic acid, so moderate consumption.
Look-alikes: Clover (Trifolium) has rounder leaflets and lacks the sour taste; both are edible.
Caution: Consume in moderation due to oxalic acid content; not suitable for those with kidney issues or gout.
Coming soon
Chanterelle Mushrooms
Golden-yellow funnels with false gills; appear after fall rains (typically late September onward). Sauté gently in butter.
Caution: Never eat raw; cook thoroughly. False chanterelles (Hygrophorellus aurantiacus) have true gills and are toxic—chanterelles have forked ridges.
Oregon Grape
Blue-black berries on thorny shrubs; ripen in late September and October. Tart and astringent; use for jelly or fermented drinks.
Caution: Berries are safe; roots and stems contain berberine and should not be harvested without expert knowledge.
Acorns (Garry Oak)
Large acorns from native Garry oak trees; leach tannins in water for several days, then dry and grind into flour. Harvest in October.
Caution: Leaching is essential to remove bitter tannins; unprocessed acorns are inedible.
Safety in this area
- Ticks are active in fall; wear long sleeves and pants, tuck pants into socks, and check your body after foraging. Remove ticks promptly with tweezers.
- Poison oak (Toxicodendron pubescens) grows in dry, open areas; learn to identify its three-leaflet clusters and avoid contact. Wash skin and clothes immediately if exposed.
- Giant hogweed (Heracleum mantegazzianum) causes severe phytophotodermatitis; it has large white flower clusters and grows near water. Do not touch; report sightings to King County Noxious Weed Control.
- Forage only on public land or with explicit permission from the landowner. State parks and national forests allow foraging for personal use; check specific rules at your destination.
Foraging information is educational. Confirm every identification with a regional field guide or expert before eating anything wild.
