Fall Foraging in Grand Forks: September Harvest

In season now

  • Wild Grape (Vitis riparia)

    Where: Thickets, fence rows, and riverbank tangles along the Red River and tributary corridors.

    Dark purple-black clusters ripen now; tart, seedy fruit best used for juice, jelly, or wine. Harvest by cutting entire bunches with pruners.

    Look-alikes: Pokeweed berries are similar but grow in drooping clusters and are toxic; grape clusters hang in tight bunches and vines have tendrils.

    Caution: Wear long sleeves—briars and ticks are abundant in dense thickets.

  • Wild Plum (Prunus americana)

    Where: Shelterbelts, field margins, and scrubby draws throughout the region.

    Red to yellow fruits (2–3 cm) ripen mid-to-late September; firm flesh, large pit. Excellent raw or cooked into preserves.

    Look-alikes: Chokecherry is smaller (0.8 cm), darker, and more astringent; wild plum is larger and less puckering.

    Caution: Check for ticks after harvesting in tall grass. Avoid private land without permission.

  • Chokecherry (Prunus virginiana)

    Where: Shelterbelts, roadsides, and riparian margins; common throughout the Red River Valley.

    Small dark-purple berries in drooping clusters; very astringent raw but excellent for syrup, jelly, and wine. Pit is safe (unlike apricot pits).

    Look-alikes: Black elderberry has similar clusters but berries are larger and grow in flatter cymes; chokecherry clusters are distinctly drooping.

    Caution: Leaves and stems contain cyanogenic compounds—use only ripe fruit. Ticks are common in harvest areas.

  • Highbush Cranberry (Viburnum opulus subsp. americana)

    Where: Moist thickets, wetland margins, and riparian shrublands near the Red River.

    Bright red translucent berries in flat clusters persist into fall; tart, gelatinous, best used for sauce or jelly. Harvest after first light frost for best flavor.

    Look-alikes: Guelder rose (ornamental) is nearly identical but often treated with pesticides; forage only wild plants far from gardens.

    Caution: Wetland areas harbor ticks and mosquitoes; wear repellent and check skin after foraging.

  • Puffball Mushrooms (Lycoperdon & Calvatia spp.)

    Where: Open grasslands, prairie remnants, and field margins; often after rain.

    White, round, firm fruiting bodies (5–15 cm) are edible when interior is uniformly white throughout. Slice, bread, and fry or add to soups.

    Look-alikes: Young buttons of toxic Amanita species are white but have a cup-like volva at the base and gills inside; puffballs are solid white throughout.

    Caution: Cut open every specimen to confirm solid white interior. Do not forage on treated agricultural land.

  • Wild Mint (Mentha arvensis)

    Where: Ditches, wetland margins, and disturbed moist ground throughout the region.

    Aromatic leaves with square stems; fresh or dried for tea, seasoning, or infusions. Harvest before frost kills the plant.

    Look-alikes: Catnip (Nepeta cataria) is similar but has a distinct catmint scent; wild mint smells clean and peppery.

    Caution: Ensure positive ID before harvesting. Avoid ditches treated with herbicides.

Coming soon

  • Hazelnut (Corylus americana)

    Nuts mature in late September–early October; brown husks split to reveal hard-shelled nuts. Crack and eat raw or roast for deeper flavor.

  • Wild Rose Hips (Rosa woodsii & R. acicularis)

    Hips ripen after frost and persist through winter; high in vitamin C. Dry, steep for tea, or simmer into syrup.

  • Staghorn Sumac (Rhus typhina)

    Fuzzy red berry clusters persist into fall; steep in cold water for tart 'sumac-ade' or dry for spice. Avoid white-berried species (toxic).

Safety in this area

  • Ticks are abundant in tall grass, brush, and riparian areas through September; wear long sleeves and pants, check skin thoroughly after foraging, and remove ticks promptly.
  • Poison ivy (three leaflets, glossy, red in fall) grows in thickets and along riverbanks; learn to identify and avoid contact.
  • Giant hogweed is not established in North Dakota, but always verify plant ID before harvest—when in doubt, leave it.
  • Private land requires explicit permission; most productive foraging habitat (shelterbelts, riparian corridors) is privately owned—ask first.

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