The Vaccinium Genus: Blueberries and Bilberries
The genus Vaccinium accounts for several of the most widely distributed edible berry species in Canada. Wild blueberry (Vaccinium angustifolium) grows across Atlantic Canada, Quebec, and Ontario, typically in acidic, well-drained soils on rocky barrens and open hillsides. The berries are small — rarely exceeding 8 mm — with a powdery bloom and a five-pointed star-shaped calyx scar at the crown.
Lowbush plants reach 15–60 cm in height, with small, elliptical leaves that turn bright red in autumn. Flowers appear in May as small, urn-shaped white bells, often before the leaves are fully open. The berry ripens to a deep blue-purple between July and August depending on latitude.
Bog Bilberry and Dwarf Bilberry
Bog bilberry (Vaccinium uliginosum) occupies wetter habitats — sphagnum bogs and tundra margins — and is common across northern boreal zones and alpine areas. Its fruit is often dusty blue with a notably sweet-tart flavour. Dwarf bilberry (V. caespitosum) is found in subalpine and alpine zones in the Rockies and coastal mountains of British Columbia, growing in dense low mats.
Saskatoon: Amelanchier alnifolia
The saskatoon (Amelanchier alnifolia) is arguably the most culturally significant wild berry in western Canada. It ranges from BC to Manitoba and into Ontario, growing as a multi-stemmed shrub up to 4 metres in disturbed areas, forest edges, and river valleys. The berries are dark purple to nearly black when ripe, roughly 8–15 mm in diameter, with a juicy, mildly sweet pulp.
Flowering occurs very early in spring — often April to May — before the leaves are fully open. The white five-petalled flowers are distinctive and occur in dense racemes. Leaves are rounded to oval, with coarse teeth in the upper half and smooth margins near the base.
Bearberry: Arctostaphylos uva-ursi
Bearberry, or kinnikinnick (Arctostaphylos uva-ursi), is a low-growing, mat-forming evergreen found on exposed, well-drained soils across much of Canada, from BC's interior to the Atlantic coast. The berries are bright red, smooth, and about 6–10 mm in diameter, persisting on the plant through winter.
While technically edible, bearberries are mealy, nearly tasteless, and very dry. They are eaten by bears and birds rather than preferred by human foragers. Their value in this context is as a reliable identification reference — the combination of evergreen spatula-shaped leaves with red winter berries is distinctive and unmistakable in the boreal understory.
Buffaloberry: Shepherdia canadensis
Canada buffaloberry (Shepherdia canadensis) is a nitrogen-fixing shrub found from BC to the Maritimes, common along streams and at forest edges. The berries are yellow to red, translucent, and ripen in mid-summer. They have a distinctive bitter-sour flavour due to saponin content and are best used for jelly rather than eaten raw in quantity.
The leaves are a reliable identifier: oval with a silvery-scaly underside and rust-brown scales on the upper surface, a pattern found in no other common Canadian shrub. Stems also carry rust-brown scales. The plant is dioecious — only female plants bear fruit.
Red Elderberry vs. Blue Elderberry
Two elderberry species occur in Canada and their correct identification matters significantly. Blue elderberry (Sambucus nigra ssp. caerulea) is found in BC and produces berries that, when fully ripe and cooked, are edible and widely used for preserves. Red elderberry (Sambucus racemosa) occurs across most of Canada and produces bright red berries in conical clusters — these are toxic raw and should not be consumed.
The cluster shape is the easiest field distinction: blue elderberry produces flat-topped clusters (corymbs), while red elderberry produces elongated pyramidal clusters. Both have compound leaves with 5–9 leaflets and deeply furrowed, pithy stems.
Raw elderberries of any species contain cyanogenic glycosides and should not be eaten uncooked in significant amounts. This applies even to blue elderberry.
Highbush Cranberry: Viburnum opulus var. americanum
Despite the name, highbush cranberry is not a true cranberry — it belongs to the genus Viburnum. The bright red berries ripen in September and persist into winter. They are sharply tart when raw but soften considerably after a frost, making them suitable for jelly and sauce. The three-lobed maple-like leaves and flat-topped white flower clusters in June are diagnostic.
A European lookalike, Viburnum opulus (European highbush cranberry), is occasionally naturalized in urban areas and is considered less palatable due to higher tannin content, though it is not toxic.
Thimbleberry: Rubus parviflorus
Thimbleberry (Rubus parviflorus) grows in disturbed forests, roadsides, and logged areas from BC to Ontario and into northern Ontario. The large, soft red berries lack the central core of raspberries, collapsing slightly when picked. The fruit is edible but very fragile and does not transport well — best eaten on site.
The plant is unmistakable: large, soft maple-shaped leaves up to 25 cm across, white flowers with crinkled petals, and no prickles on the stems (unlike most other Rubus species).
Summary: Field Identification Points
- Check the calyx scar on any small blue or black berry — five points confirms Vaccinium
- Saskatoon clusters are rounded and compact; chokecherry hangs in elongated racemes
- Bearberry leaves are evergreen, spatula-shaped, and leathery — distinctive in winter
- Buffaloberry leaves have rust-brown scales on both surfaces; no other common Canadian shrub matches this
- Elderberry cluster shape separates blue (flat-topped) from red (pyramidal)
- Highbush cranberry has three-lobed leaves and persists through winter on the stem
