In season now
Black Walnut
Where: Scattered throughout Philadelphia neighborhoods, parks, and along the Schuylkill and Delaware rivers; common in older residential areas.
Green husks are turning brown and falling now; crack open to reveal the hard black shell inside. Harvest husks before they blacken completely, wear gloves (they stain permanently), and cure nuts in a dry place for 2–4 weeks before cracking.
Look-alikes: Butternut has a more elongated, sticky husk and is much less common here; black walnut husks are rounder and more abundant.
Caution: Walnut hulls contain juglone, which kills many plants—don't compost near gardens.
Pawpaw
Where: Scattered in moist understory areas along the Schuylkill River, Wissahickon Creek, and other riparian zones; rare but present in Philadelphia parks.
Fruit is 7–13 cm (3–5 in) long, greenish-yellow, and soft when ripe; flesh is custard-like and sweet. Pick when slightly soft and eat fresh or freeze pulp for later use.
Look-alikes: No dangerous look-alikes; fruit is distinctive.
Caution: Pawpaw leaves and twigs contain acetogenins—don't eat them. Fruit is fragile and ferments quickly.
Persimmon (American)
Where: Scattered in open woodlands, field edges, and disturbed areas throughout the Philadelphia region; common in South Jersey and southern suburbs.
Orange fruit 2–5 cm (1–2 in) across ripens as frost approaches; must be fully soft and translucent to eat (astringent otherwise). Harvest after first light frost or wait until they fall and are soft.
Look-alikes: No dangerous look-alikes; fruit is distinctive.
Caution: Unripe fruit is extremely astringent and inedible—patience is essential.
Grape (Wild)
Where: Abundant along stream banks, fence lines, and woodland edges throughout Philadelphia and surrounding counties.
Dark purple or black clusters ripen now; eat fresh or use for juice and jelly. Grapes are high in seeds but flavorful; strip berries from stems by hand.
Look-alikes: Virginia creeper berries are blue-black and similar-sized but are toxic; check for tendrils with adhesive discs (Virginia creeper) vs. simple tendrils (grape).
Caution: Virginia creeper is common in the same habitat—learn the difference before harvesting.
Hickory Nuts
Where: Scattered throughout Philadelphia parks, neighborhoods, and woodlands; shagbark and pignut hickory are most common.
Nuts fall from mid-September onward; crack open the husk to access the hard shell. Shagbark nuts are larger and easier to crack; pignut nuts are smaller and require more effort.
Look-alikes: Black walnut is similar but has a rounder, stickier husk and is more abundant.
Caution: Distinguish shagbark (shaggy bark, larger nuts) from pignut (smooth bark, smaller nuts) before investing effort in cracking.
Autumn Olive
Where: Invasive shrub common along roadsides, disturbed areas, and field edges throughout the Philadelphia region.
Red or orange berries speckled with silver are ripe now; tart and high in lycopene. Eat fresh or make into jam; berries are small but prolific on a single plant.
Look-alikes: No dangerous look-alikes; berries are distinctive.
Caution: This is an invasive species—harvest enthusiastically to help control it.
Coming soon
Acorn (White Oak)
White oak acorns are lower in tannins and can be eaten with less processing than red oak acorns. Leaching in cold water for 1–2 weeks removes bitterness; roast and grind for flour or eat as nuts.
Mushrooms (Fall Species)
Oyster, hen of the woods, and sulfur shelf mushrooms fruit in October–November. Never eat wild mushrooms without expert ID; join a local mycological society or forage with an experienced guide.
Wintercress
Young rosettes appear in late fall and overwinter; harvest leaves in spring for a peppery salad green. Sow seeds now in disturbed areas if you want to establish a patch for next year.
Safety in this area
- Ticks are active through fall in Philadelphia—wear long sleeves and pants, tuck pants into socks, and check yourself thoroughly after foraging. Lyme disease and other tick-borne illnesses are common in Pennsylvania.
- Poison ivy is abundant in woodlands and along streams; learn the three-leaflet pattern and avoid it. Urushiol oil persists on clothing and tools—wash immediately after contact.
- Giant hogweed is present in some areas of the Delaware and Schuylkill river corridors; it causes severe phytophotodermatitis (blistering) when sap contacts skin in sunlight. Avoid any large white-flowered umbels with thick, hairy stems.
- Private land: Always ask permission before foraging on private property. Many parks and natural areas in Philadelphia require permits or have foraging restrictions—check with the Parks & Recreation Department and local land trusts before harvesting.
Foraging information is educational. Confirm every identification with a regional field guide or expert before eating anything wild.
