Features & Attributes

Prime-Ark® Blackberry features showy clusters of white star-shaped flowers along the branches from early to mid summer. It has green foliage throughout the season. The fuzzy oval compound leaves do not develop any appreciable fall color. It features an abundance of magnificent black berries from late summer to mid fall.

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, Prime-Ark® Blackberry is sutiable for the following landscape applications;

  • Mass Planting
  • Naturalizing And Woodland Gardens
  • Orchard/Edible Landscaping

Planting & Growing

Prime-Ark® Blackberry will grow to be about 10 feet tall at maturity, with a spread of 10 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 prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. 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.
