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.
