Illini Hardy Blackberry
Grouseberry

The Illini Hardy Blackberry was developed in Illinois for northern growers, and produces a large, juicy blackberry with medium-sweet flavor. The berries are ready for harvest in midsummer, and go great in preserves.

The Illini Hardy Blackberry, or the Illinois Blackberry, are floricanes, primarily fruiting on second year canes. Each spring cut back all two-year old canes, leaving only the last year’s growth. This is a self-pollinating variety, so it doesn’t require a second plant nearby to set fruit.

Grouseberry is a native, low-growing deciduous shrub known for its edible red berries. In early summer, it produces small, urn-shaped flowers ranging from white to pink that attract bees and other pollinators. The berries provide an important food source for many types of wildlife, including game birds such as grouse, which gives the plant its common name. People can also enjoy the berries fresh or in baked goods, though they can be difficult to harvest in large quantities.

Spreading by rhizomes, Grouseberry forms dense, broom-like mats that help stabilize soil and prevent erosion, while also providing cover for ground-nesting wildlife. It is commonly found beneath conifers in open forests, subalpine meadows, and occasionally on rocky slopes in mountainous regions. It is well-suited for naturalization, ecological restoration, and soil stabilization projects.
