In season now
Wild Grapes (Vitis riparia, V. vulpina)
Where: Thickets, fence lines, and disturbed areas throughout the Ottawa Valley; common along the Rideau River and Gatineau River corridors.
Dark purple-black clusters ripen now; small, tart, and seedy but excellent for jelly or juice. Harvest by cutting entire clusters with pruners.
Look-alikes: Pokeweed berries (Phytolacca americana) are similar in color but grow in elongated drooping clusters and are toxic; grape clusters are more compact and grow on woody vines with tendrils.
Caution: Confirm vine identity before harvesting—only true grapes have tendrils and woody stems.
Wild Raspberries & Blackberries (Rubus spp.)
Where: Field edges, clearings, and disturbed ground throughout the region; prolific in sandy or gravelly soils.
Late-season black raspberries and blackberries are at peak ripeness now; pick only fully black berries by gently rolling them off the cane into your palm.
Look-alikes: No toxic look-alikes; immature red berries are simply unripe and sour but harmless.
Caution: Wear long sleeves—thorns are sharp and abundant.
Autumn Olive (Elaeagnus umbellata)
Where: Hedgerows, roadsides, and disturbed margins; invasive but abundant in the Ottawa area.
Small red-speckled berries ripen now and are tart-sweet; high in lycopene. Eat fresh or dry for later use.
Look-alikes: No dangerous look-alikes; the distinctive silvery leaves and thorny stems are unique.
Caution: Invasive species—harvesting helps control spread.
Highbush Cranberry (Viburnum opulus subsp. americanum)
Where: Moist woodlands, swamp margins, and riparian zones; common near Ottawa's wetland areas.
Bright red berries cluster at branch tips now; tart and firm, best used for jelly or sauce after a frost (which concentrates sugars). Harvest by cutting entire berry clusters.
Look-alikes: Guelder rose (Viburnum opulus subsp. opulus, an ornamental) is nearly identical but less common in wild settings; both are edible.
Caution: Berries contain a small amount of iridoid glycosides; cooking neutralizes any mild astringency.
Wild Mint (Mentha arvensis, M. spicata)
Where: Moist disturbed ground, ditches, and stream margins throughout the region.
Leaves are at peak flavor now before frost; pinch off the top 10 cm (4 in) of stems. Dry or use fresh for tea.
Look-alikes: Catnip (Nepeta cataria) has similar leaves but a different smell and hairier stems; it is harmless but less flavorful.
Caution: Mint spreads aggressively—harvest generously to control it.
Jewelweed (Impatiens capensis, I. pallida)
Where: Wet woodlands, stream banks, and shaded moist areas throughout the Ottawa Valley.
Seed pods mature now and pop open when touched; the seeds inside are edible raw or cooked and taste like walnuts. Collect by gently pressing ripe pods over a container.
Look-alikes: No dangerous look-alikes; the succulent stems and distinctive flowers are unmistakable.
Caution: Harvest only from abundant patches; this plant is valued for poison ivy relief and should not be over-harvested.
Coming soon
Wild Mushrooms (Boletus, Chanterelle, Hen of the Woods)
Peak season begins mid-September after rain and cool nights; requires expert identification—beginners should forage with an experienced guide or mycologist.
Acorns (Quercus spp.)
White oak acorns fall in late September and are lower in tannins; leach and roast for flour or nut butter.
Hazelnuts (Corylus americana)
Nuts mature in late September; crack shells and eat raw or roasted.
Safety in this area
- Ticks are active through September in tall grass and brush—wear long sleeves and pants, tuck pants into socks, and check your body thoroughly after foraging.
- Poison ivy (Toxicodendron radicans) is common in disturbed areas and along forest edges; remember 'leaves of three, let it be'—all parts cause severe skin reactions year-round.
- Giant hogweed (Heracleum mantegazzianum) is rare but present in Ottawa; its clear sap causes phytophotodermatitis (severe burns) in sunlight—avoid any tall white-flowered umbellifers you cannot positively identify.
- Always forage on public land or with explicit permission; much of the Ottawa area is private property or protected greenspace with restricted harvesting.
Foraging information is educational. Confirm every identification with a regional field guide or expert before eating anything wild.
