Small Cranberry is a native evergreen groundcover found in bogs, fens, and wet meadows. It produces delicate pink flowers that attract a variety of pollinators, including bees, and it serves as both a nectar source and host plant for the Bog Fritillary (Boloria eunomia) butterfly. By late summer, the plant bears deep red berries that are eaten by both wildlife and people. With their high pectin content, the berries are well-suited for making jams and jellies.

Often creeping among sphagnum moss, Small Cranberry thrives in cold, acidic, and nutrient-poor soils (pH 2.9–4.7), making it well adapted to northern wetland environments. With its woody stems, it is technically classified as a shrub and often described as a subshrub or dwarf shrub. It is also valuable for wetland restoration and naturalisation projects.

Note: We use Small Cranberry for Vaccinium oxycoccos. This species is also known by many other common names, including Bog Cranberry, Small Bog Cranberry, and others. Please confirm the scientific name to ensure you are ordering the correct plant.

Black Crowberry is a native evergreen shrub that forms low, spreading mats. It has unique foliage that spirals around the stem, and small dark berries, giving it visual appeal. The berries are edible, but can be acidic, so they are not generally eaten fresh. In colder climates, the berries develop a sweet-tart flavor and are often dried or used in desserts, jams, and jellies.

This hardy shrub provides food for birds and mammals, while its flowers attract pollinators such as bees. It also serves as a host plant for certain butterflies and moths. Together, these roles make it a key contributor to the health of tundra and boreal ecosystems.

In Newfoundland and Labrador, the berries are known locally as ‘blackberries’ and are enjoyed in jams, jellies, and traditional baked goods such as buns and puddings. In Scandinavia, they continue to be used in liqueurs, wines, and juices.
