Duluth Fall Foraging: September

In season now

  • Wild grapes (Vitis riparia)

    Where: Thickets, forest edges, and along Superior shoreline; common in St. Louis River estuary

    Dark purple-black clusters ripen now; grapes are 6–10 mm across with thin skins and large seeds. Eat fresh, freeze for later, or make juice; seeds are edible but bitter.

    Look-alikes: Pokeweed berries are similar but grow in drooping clusters and are toxic; grape clusters hang upright and individual berries are attached to a central stem.

    Caution: Ensure you're harvesting from public land or have permission; Superior shoreline is mostly public but check local access rules.

  • Wild plums (Prunus americana)

    Where: Thickets, old homesteads, and disturbed areas; scattered throughout Duluth region

    Red to yellow fruits 2–3 cm across ripen late August through September; firm flesh with a single large pit. Excellent raw, or cook down for jam.

    Look-alikes: Chokecherries are smaller (8–10 mm), darker, and grow in tight clusters; wild plums are larger and grow singly or in small groups.

    Caution: Chokecherries are edible but astringent; never confuse with buckthorn berries, which are toxic and grow in dense clusters.

  • Autumn olive (Elaeagnus umbellata)

    Where: Disturbed areas, roadsides, and old fields; invasive but abundant in Duluth area

    Speckled red berries 8–10 mm long ripen September–October; tart and tangy with a large seed. Eat fresh or blend into smoothies; high in lycopene.

    Look-alikes: Goji berries are similar but rare in Minnesota; autumn olive has distinctive silvery-scaled leaves and thorny stems.

    Caution: Invasive species—harvesting helps control it; wear gloves (thorny stems) and watch for ticks in tall vegetation.

  • Staghorn sumac (Rhus typhina)

    Where: Roadsides, disturbed areas, and forest edges; very common around Duluth

    Fuzzy red berry clusters (drupes) persist through fall; steep in cold water for 15 minutes to make tart 'sumac-ade.' Strain well to remove fine hairs.

    Look-alikes: Poison sumac (Toxicodendron vernix) has white or cream berries and grows in wet areas; staghorn sumac has red berries and fuzzy stems.

    Caution: Poison sumac is extremely toxic; never harvest from wet areas. Wear gloves and wash hands thoroughly after handling.

  • Wild mushrooms: Honey mushroom (Armillaria mellea)

    Where: Dead logs and stumps in mixed forests; common in Superior National Forest and Duluth parks

    Golden-yellow caps 3–8 cm, white gills, ring on stem, and clustered growth. Cook thoroughly (never eat raw); sauté or pickle.

    Look-alikes: Deadly Galerina marginata is tiny (1–3 cm) with a ring and grows on rotting wood; honey mushrooms are much larger and grow in dense clusters.

    Caution: Misidentification can be fatal; forage only if you are 100% certain of your ID or go with an experienced local forager.

  • Jewelweed (Impatiens capensis)

    Where: Wet areas, stream banks, and shaded low ground throughout Duluth region

    Orange or yellow flowers now; crush fresh stems and rub juice on skin for poison ivy relief. Use immediately after harvest for best effect.

    Look-alikes: No dangerous look-alikes; distinctive orange trumpet flowers and succulent translucent stems are unmistakable.

    Caution: Grows in tick-prone wet areas; check yourself thoroughly after harvesting. Poison ivy often grows nearby—learn to ID it before you forage.

Coming soon

  • Wild cranberries (Vaccinium oxycoccos, V. macrocarpon)

    Tart red berries ripen October–November in sphagnum bogs; excellent for sauce and storage. Check Minnesota DNR for bog access and harvest limits.

  • Acorns (Quercus spp.)

    White oak acorns fall September–October and are lower in tannins than red oak; leach and roast for flour or nut butter.

  • Wintergreen (Gaultheria procumbens)

    Bright red berries persist into winter in coniferous forests; minty flavor works fresh or steeped for tea. Harvest sparingly from public land only.

Safety in this area

  • Ticks are active through fall in tall grass and brush; check yourself and pets daily, especially after harvesting in disturbed areas or near water.
  • Poison ivy (three leaflets, waxy appearance) is common in Duluth; learn to ID it before foraging—all parts are toxic year-round, including winter stems.
  • Giant hogweed does not occur in Minnesota, but wild parsnip (Pastinaca sativa) causes phytophotodermatitis; never touch or harvest any white-flowered umbellifers unless you are certain of ID.
  • Respect private land: most productive foraging areas near Duluth are on private property or Superior National Forest—ask permission or stick to public parks and shoreline.

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