Cascade Blueberry

The Cascade Blueberry is a low-growing, deciduous shrub with sweet, candy-like berries prized by hikers and wildlife alike! (Hence the species name "deliciousum".)  

Edible Uses

Cascade Bilberry produces small, deeply flavored berries, often described as sweeter and more aromatic than most huckleberries [1]. They can be enjoyed fresh, dried, frozen, or cooked into jams, pies, syrups, and baked goods [1][2].
Nutritionally, they’re rich in vitamin C, with smaller amounts of A and B vitamins, minerals such as potassium and iron, and powerful anthocyanin antioxidants [3]. These compounds support circulation, boost immunity, and provide the berry’s rich color.

Ornamental Qualities

This low, rhizomatous shrub forms attractive clumps, usually 1–3 feet tall, with delicate, pinkish urn-shaped flowers in late spring [4]. In fall, its foliage often glows red or bronze, making it a subtle but striking groundcover in alpine gardens.
Pair it with other acid-loving species in our nursery, such as Evergreen Huckleberry, Oval-leaf Huckleberry, or native ferns. For more structure, consider pairing with Blue Blossom Ceanothus—just don’t let it block the sunlight.

Environment and Culture

Cascade Bilberry is native to subalpine and alpine meadows and open conifer forests from British Columbia through Washington, Oregon, and into northern California, usually between 2,000–6,500 feet elevation [1][4].
The berries are an essential food source for bears, birds, and small mammals [5]. Indigenous peoples of the Pacific Northwest—such as the Interior Salish and others—traveled to high elevations each summer to harvest them. Some communities used fire to encourage larger berry patches and improve productivity [6]. Despite cultural disruption, Indigenous stewardship of Vaccinium species continues today, and both the people and the plants deserve our respect, gratitude, and reparations.

Harvest, Care, and Preparation

Cascade Bilberry can be challenging to cultivate outside of its cool mountain range but rewards patience. It prefers acidic (pH 4.5–6), well-drained, organic-rich soils—mimicking forest duff. Shallow roots benefit from mulch with pine needles, bark, or rotting wood.

• Watering: Keep soil consistently moist for 1–3 years. Supplemental summer water increases yield.

• Heat: Young plants are sensitive to summer heat and may need partial shade in hot, low-elevation gardens.

• Harvest: Expect berries in 2–4 years, ripening mid-summer to late August [1][2]. Use them as you would blueberries—fresh, dried, baked, or preserved.
