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.

Grouseberry is a native, low-growing deciduous shrub known for its edible red berries. In early summer, it produces small, urn-shaped flowers ranging from white to pink that attract bees and other pollinators. The berries provide an important food source for many types of wildlife, including game birds such as grouse, which gives the plant its common name. People can also enjoy the berries fresh or in baked goods, though they can be difficult to harvest in large quantities.

Spreading by rhizomes, Grouseberry forms dense, broom-like mats that help stabilize soil and prevent erosion, while also providing cover for ground-nesting wildlife. It is commonly found beneath conifers in open forests, subalpine meadows, and occasionally on rocky slopes in mountainous regions. It is well-suited for naturalization, ecological restoration, and soil stabilization projects.
