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.

Rocky Mountain Fescue is a native perennial bunchgrass recognized for its fine-textured clumps and adaptability to harsh environments. It grows well in dry, rocky, and nutrient-poor soils and is highly cold-tolerant, making it well-suited to both prairie and alpine habitats. Its fibrous root system contributes to soil stability and helps reduce erosion on slopes and shallow soils.
Widespread across western and northern North America, Rocky Mountain Fescue is an important component of many prairie and alpine ecosystems. It contributes ground cover and organic matter that support soil function, provides cover for small wildlife, and offers moderate forage for grazing animals. Hardy and versatile, it is used in ecological restoration, naturalization, and habitat enhancement projects, particularly in upland and alpine landscapes.
