Cascade Jewel Huckleberry is a tetraploid evergreen cultivar of Vaccinium ovatum developed by Oregon State University, representing a significant leap forward in native plant breeding. This shrub grows 36 to 42 inches tall and produces medium to large, shiny purple-black berries throughout summer that deliver a complex flavor far beyond typical blueberries. Hardy in zones 7 through 9 and thriving in partial sun with acidic soil, this variety combines the ornamental appeal of an evergreen with genuine edible interest, making it a distinctive addition to gardens seeking something beyond the ordinary.

Cascade Jewel emerges from deliberate breeding work at Oregon State University, not wild collection, which gives it superior nursery performance and more vigorous growth than its wild relatives. The berries pack a tart-sweet profile with what growers describe as a wild forest character, delivering layers of flavor that blueberries simply cannot match. Its evergreen foliage keeps the plant visually interesting year-round, while the shiny purple-black berries create genuine visual drama when they ripen in summer.
The edible berries can be eaten fresh off the bush, their complex sweet-tart flavor rewarding immediate snacking. Their distinctive wild forest character also lends itself to jam making, pies, and baking applications where the deeper flavor profile can shine alongside other ingredients. The evergreen foliage and dense growth habit make it suitable as an ornamental landscaping plant beyond its fruit production.

Berries ripen through summer, reaching their full sweet-tart character when they turn shiny purple-black and feel slightly soft to the touch. Harvest by hand, gently rolling ripe berries into your palm; they should release from the branch with minimal resistance. Multiple harvests throughout the summer season are possible as berries mature in succession rather than all at once.

“Cascade Jewel was developed by Oregon State University as a deliberate cultivar of the native Oregon evergreen huckleberry, Vaccinium ovatum. Rather than collecting seed from wild stands, breeders created this tetraploid variety, meaning it has four sets of chromosomes instead of the typical two, which translates into improved vigor and superior performance in cultivation. This advancement in native plant breeding bridges the gap between wild huckleberries and cultivated berries, making a traditionally gathered plant accessible to home gardeners without sacrificing the authentic flavor that has made wild huckleberries treasured in the Pacific Northwest for generations.”
