Thimbleberry

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.

Thimbleberry is an ornamental shrub with large, green maple-like-leaves. Flowers are attractive, fragrant, and turn into red-raspberry-like berries. The berries are good for jams, cakes, breads, muffins etc. If you remove the berry, the core resembles a thimble, giving this shrub its namesake.
