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.
