This is an open multi-stemmed deciduous shrub with an upright spreading habit of growth. Its relatively coarse texture can be used to stand it apart from other landscape plants with finer foliage. This is a high maintenance plant that will require regular care and upkeep. Each spring, cut back all dead and two-year old canes to the ground, leaving only last year's growth standing. It is a good choice for attracting birds to your yard. Gardeners should be aware of the following characteristic(s) that may warrant special consideration;

  • Suckering
  • Disease
  • Spiny

Aside from its primary use as an edible, Illini Hardy Blackberry is sutiable for the following landscape applications;

  • Mass Planting

  • Orchard/Edible Landscaping

Planting & Growing

Illini Hardy Blackberry will grow to be about 5 feet tall at maturity, with a spread of 4 feet. It tends to be a little leggy, with a typical clearance of 2 feet from the ground, and is suitable for planting under power lines. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 10 years. This is a self-pollinating variety, so it doesn't require a second plant nearby to set fruit.

This shrub may not always play well with others; as such, it is best grown in its own designated garden space or isolated area of an edibles garden. It should only be grown in full sunlight. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This particular variety is an interspecific hybrid. It can be propagated by division; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.
