Blue Boy Clematis

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.

Blue Boy Clematis is a cold-hardy, fast growing, woody climbing vine. Hundreds of stunning steel-blue bell shaped flowers adorn the vine throughout the summer that droop and appear to hang in the air. The fibrous stems spread and create a fan-like symmetry shape.

This species will do best with support from a trellis, fence, or even other shrubs or tree stumps.

The Blue Boy Clematis was developed in Manitoba, Canada in 1947 by famous breeder Frank L. Skinner by crossing C. integrifolia x C. viticella, but it didn’t gain popularity until the 1990’s.
