Fall Foraging in Portland, Maine: September

In season now

  • Wild Grapes (Vitis spp.)

    Where: Woodland edges, fence lines, and disturbed areas throughout greater Portland; look for vines climbing trees and shrubs.

    Clusters of dark purple or black berries, each about pea-sized, with 2–4 hard seeds inside; taste tart and sweet. Pick ripe berries (they don't ripen further after harvest) and eat raw, or cook down with sugar for jelly.

    Look-alikes: Pokeweed berries are similar but grow in drooping clusters and are poisonous; wild grape berries grow in tight clusters and have visible seeds.

  • Autumn Olive (Elaeagnus umbellata)

    Where: Roadsides, field margins, and disturbed ground; invasive shrub now widespread in southern Maine.

    Small red or orange berries speckled with silver, 8–10 mm long, tart and slightly astringent. Eat raw or blend into smoothies; high in lycopene. Harvest when fully colored.

    Look-alikes: No dangerous look-alikes; distinctive silver speckles are diagnostic.

  • Highbush Blueberry (Vaccinium corymbosum)

    Where: Wetland margins, sandy soils, and open woodlands; common throughout the Portland area.

    Dark blue berries, 10–15 mm, waxy bloom, sweet and mild. Pick by hand or shake branches over a cloth; eat fresh or freeze.

    Look-alikes: Pokeweed berries are similar but grow in drooping clusters and are poisonous; blueberries grow in tight clusters on woody shrubs.

  • Wild Mushrooms: Hen of the Woods (Maitake, Grifola frondosa)

    Where: Base of oak trees in mixed hardwood forests; most common in September and October.

    Large, gray-brown, shelf-like fruiting body with wavy, overlapping caps; firm, white flesh; earthy, rich flavor. Cut at base with a knife; sauté or roast.

    Look-alikes: Polypores and other shelf fungi lack the distinctive frilly, overlapping structure and dense clustering of maitake.

  • Wild Mushrooms: Chicken of the Woods (Laetiporus sulphureus)

    Where: Dead or dying hardwood logs and stumps, especially oak; visible through September.

    Bright orange and yellow shelf-like fruiting body, soft and spongy when young, with small pores underneath. Cook thoroughly before eating; raw can cause gastric upset. Sauté or roast.

    Look-alikes: Jack O'Lantern mushroom (Omphalotus) glows faintly in dark and has gills (not pores); Chicken of the Woods has pores and does not glow.

  • Wild Mushrooms: Oyster Mushroom (Pleurotus ostreatus)

    Where: Hardwood logs and stumps, especially beech and birch; fruiting through fall.

    Shelf-like caps, gray to brown or white, with white gills running down to the stem; mild, slightly sweet flavor. Cut at base; sauté or roast. Firm, meaty texture.

    Look-alikes: Angel Wings (Coprinellus disseminatus) are thinner, more delicate, and grow in dense clusters; Oyster mushrooms are larger and more robust.

Coming soon

  • Acorns (White Oak, Quercus alba)

    Large, smooth acorns with shallow caps; lower tannin content than red oak. Crack, leach in cold water for 1–2 weeks (changing water daily), then dry and grind into flour.

  • Walnuts (Black Walnut, Juglans nigra)

    Large, round, green husks turning brown; hard shell inside. Harvest when husks darken; cure in sun for 2–4 weeks, crack, and extract nutmeat.

  • Wintergreen (Gaultheria procumbens)

    Bright red berries and glossy evergreen leaves with minty scent when crushed; available through winter. Eat berries raw or steep leaves for tea.

Safety in this area

  • Tick season is active through fall in Maine; wear long sleeves and pants, tuck pants into socks, and check skin thoroughly after foraging. Lyme disease and other tick-borne illnesses are endemic.
  • Poison ivy (three leaflets, glossy, red in fall) and poison oak are common in woodlands and field edges; learn to identify and avoid contact.
  • Giant hogweed is not yet widespread in the Portland area but is present in southern Maine; avoid any tall (1–2 m), white-flowered umbellifers with large, deeply lobed leaves and hairy stems—sap causes severe phytophotodermatitis.
  • Black bears are present in inland Maine; make noise while foraging, avoid dawn and dusk, and never leave food or trash unattended. Stay on public land or obtain permission from landowners; Maine has strong trespassing laws.

Foraging information is educational. Confirm every identification with a regional field guide or expert before eating anything wild.
