Sulphur-Flower Buckwheat

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.

Sulphur-Flower Buckwheat is a native perennial wildflower known for its dense clusters of cream to yellow flowers. The long-lasting blooms persist from late spring into summer, providing an extended nectar source for a variety of pollinators. The flower buds are often red-tinted before opening. As the blooms age, they shift to orange or red, adding seasonal interest and making them well-suited to dried flower arrangements. Its seeds are also eaten by birds, adding to its ecological value.

Depending on climate and conditions, Sulphur-Flower Buckwheat may be evergreen to semi-evergreen, or its foliage may turn red during fall. Its deep roots and spreading growth stabilize rocky or sandy soils, making it useful for erosion control. Exceptionally hardy once established, it requires little care and thrives in challenging environments, making it an excellent choice for pollinator gardens, naturalization, and ecological restoration projects.
