Features & Attributes

Triple Crown Blackberry has green foliage throughout the season. The serrated oval compound leaves do not develop any appreciable fall color. The flowers are not ornamentally significant. It features an abundance of magnificent black berries in mid summer.

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

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

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

Planting & Growing

Triple Crown Blackberry will grow to be about 3 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. 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 is a selection of a native North American species. 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.
