What to Forage in August in Canada
Part of the series: Wild, Weedy, and In Your Yard: Late Summer Foraging
Key Takeaways
Late August is a peak foraging season across Canada, offering ripe fruits, late-blooming flowers, and tender greens.
Common edible plants in season now include goldenrod, rosehips, crabapples, yarrow, lamb’s quarters, and a variety of wild berries.
Harvest windows vary by region — northern areas peak earlier, coastal areas later.
Sustainable foraging means taking only what you need, leaving enough for wildlife, and respecting Indigenous harvesting rights.
Accurate plant identification and safe harvesting locations are essential for both health and ecological care.

Late August is a month of change in Canada’s landscapes. Days are still warm, but nights begin to cool. In Northern regions, the first leaves blush yellow on poplars. Fields shimmer with goldenrod, berry canes droop with fruit, and the air holds a trace of autumn. For foragers, this is a pivotal moment — the last full flush of summer growth before the pace of the season slows.
Across the country, plants are shifting from flowering to fruiting, from tender shoots to seed. In the North, the harvest window is short; a frost could come within weeks. In the Maritimes, rosehips swell along the coast while inland, blueberries reach their peak. On the Prairies, chokecherries ripen in dusty clusters along fencelines, and in the West, the last of the salmonberries give way to huckleberries.
Whether you live in a rural area or a city neighbourhood, edible wild plants are within reach. This guide offers an overview of what’s available in late August across Canada, with tips for identification, sustainable harvesting, and historical or cultural context for each species. It’s designed to be a resource you can trust — grounded in field knowledge and the long traditions of people who have harvested from these landscapes for generations.
Why August Matters
By August, many spring greens have gone bitter, and early summer fruits have either been eaten or dropped. What remains is a mix of late-blooming flowers, mid-season greens, and fruiting shrubs or trees. This is the time to collect plants at their nutritional peak, before seeds fully set and frost begins to damage leaves and fruit.
In the Canadian climate, late summer is also a transitional period for foragers. It’s an opportunity to gather food for immediate eating and to preserve a portion for winter. Many Indigenous food traditions and settler practices relied on August harvests to carry communities through the colder months.
Regional Timing
Canada’s size means harvest windows vary widely. In the Yukon and Northwest Territories, many plants ripen two to three weeks earlier than in southern regions, and frost can arrive by early September. The Atlantic provinces often see extended harvest periods into late September, especially along the coast where the ocean moderates temperature. In the Prairies, hot summers bring fruit on quickly, but dry conditions can shorten the harvest window.
Ethical Foraging Principles
Take only what you can use, leaving enough for wildlife and plant regeneration.
Avoid harvesting from private property without permission.
Steer clear of areas treated with pesticides or near high-traffic roads.
Learn and follow any regional foraging regulations.
Acknowledge and respect Indigenous harvesting rights and knowledge — much of what we know about these plants comes from those traditions.
Goldenrod (Solidago spp.)
Identification: Tall stems (up to 1.5 metres) topped with plumes of small yellow flowers. Leaves are narrow and alternate along the stem.
Habitat: Meadows, roadsides, and open fields across Canada.
Use: Flowers and young leaves can be used for tea, often blended with other herbs. Historically used in European herbalism for urinary tract health and as a mild diuretic.
Harvesting Tip: Pick flower clusters when just beginning to bloom for the best flavour. Dry in a single layer out of direct sun.
Rosehips (Rosa spp.)
Identification: The fruit of wild roses — bright red or orange, round or oval, with a smooth skin. Found on thorny shrubs.
Habitat: Hedgerows, roadsides, forest edges. Common across most of Canada.
Use: High in vitamin C, traditionally used in teas, syrups, and jams. Both Indigenous and settler communities relied on rosehips as a winter source of nutrients.
Harvesting Tip: Wait until after the first light frost to pick — it softens the fruit and mellows the flavour. Remove seeds before use, as they can be irritating.
Crabapples (Malus spp.)
Identification: Small, often tart apples less than 5 cm in diameter. Colours range from yellow to deep red.
Habitat: Old orchards, urban boulevards, and wild thickets.
Use: Jellies, sauces, ciders, and pickles. In settler traditions, crabapples were often the first apples to ripen and were prized for their pectin content.
Harvesting Tip: Choose firm, unblemished fruit. They store well in a cool place for several weeks.
Yarrow (Achillea millefolium)
Identification: Feathery, aromatic leaves; clusters of small white flowers (sometimes pink).
Habitat: Meadows, roadsides, and disturbed ground across Canada.
Use: Used in teas and poultices by many Indigenous communities for colds, fevers, and wound care.
Harvesting Tip: Pick the upper third of the plant while in bloom. Avoid harvesting in areas exposed to pollution.
Lamb’s Quarters (Chenopodium album)
Identification: Soft, triangular leaves often coated with a powdery white film.
Habitat: Gardens, fencelines, vacant lots.
Use: Edible leaves that can be eaten raw or cooked. Nutritionally similar to spinach, rich in iron and vitamins A and C.
Harvesting Tip: Younger leaves are more tender. Avoid plants that have started to flower heavily, as they can become bitter.
Wild Berries
Chokecherries (Prunus virginiana)
Dark red to black berries in clusters; astringent when raw but excellent for syrups and jellies.
Blueberries (Vaccinium spp.)
Small, sweet or tart berries; found in barrens, forests, and rocky slopes.
Blackberries (Rubus spp.)
Plump, shiny black fruit; tangy-sweet; grows in thickets and woodland edges.
Cultural Note: Berries are central in Indigenous cuisines, often dried or mixed with meat and fat for winter foods such as pemmican.
Fireweed (Chamerion angustifolium)
Identification: Tall spikes with bright pink-purple flowers; narrow, willow-like leaves.
Habitat: Open ground, recently disturbed areas, forest edges.
Use: Young leaves for tea; flowers can be used in syrups and jellies. In northern communities, fireweed is a seasonal marker and a symbol of renewal after disturbance, such as wildfires.
Harvesting Tip: Young leaves are best before the plant flowers fully.
West Coast:
Late salmonberries and huckleberries in coastal forests.
Sea plantain on rocky shorelines.
Fireweed in mountain meadows.
Prairies:
Chokecherries and saskatoon berries on fencelines.
Crabapples in rural shelterbelts.
Lamb’s quarters in disturbed soils.
Ontario and Québec:
Wild grapes climbing along riverbanks.
Goldenrod in open meadows.
Crabapples in old orchards and urban plantings.
Atlantic Canada:
Rosehips along coastal paths.
Blueberries in barrens and heathland.
Yarrow in fields and road verges.
North:
Cloudberries in bogs.
Labrador tea in wetlands.
Fireweed in open clearings.
Identification is essential: Some edible plants have toxic look-alikes. Consult reputable field guides or attend local foraging walks.
Harvest clean: Avoid plants from polluted areas (roadsides, industrial zones, sprayed fields).
Respect wildlife: Many species rely on the same food sources; never take more than a third from a single plant or patch.
Preserve knowledge: Learn from experienced foragers and acknowledge traditional Indigenous uses of these plants.
August foraging in Canada is about timing, observation, and respect for the land. The month offers a mix of fresh eating and preservation opportunities, from tart crabapples destined for jelly to goldenrod blossoms ready for drying. It’s a reminder that food isn’t just grown in fields or bought in stores — it grows in meadows, along fencelines, and in the spaces between seasons.
Whether you’re filling a basket on a coastal trail or picking a handful of lamb’s quarters from your backyard, each harvest is part of a longer tradition. One that connects you to the changing seasons, to those who foraged here before you, and to the living landscapes of Canada.
