A great small tree prized for its abundance of showy white flowers in spring and consistently beautiful fall colors; a great three-season shade tree for small landscapes

Ornamental Features

Autumn Brilliance Serviceberry is covered in stunning clusters of white flowers rising above the foliage in early spring before the leaves. It has dark green foliage throughout the season. The oval leaves turn an outstanding brick red in the fall. It produces blue berries from late spring to early summer. The smooth gray bark adds an interesting dimension to the landscape.

Landscape Attributes

Autumn Brilliance Serviceberry is an open multi-stemmed deciduous tree with a more or less rounded form. Its relatively fine texture sets it apart from other landscape plants with less refined foliage.

This is a relatively low maintenance tree, and is best pruned in late winter once the threat of extreme cold has passed. It is a good choice for attracting birds to your yard, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. It has no significant negative characteristics.

Autumn Brilliance Serviceberry is recommended for the following landscape applications;

  • Accent
  • Shade
  • General Garden Use

Planting & Growing

Autumn Brilliance Serviceberry will grow to be about 25 feet tall at maturity, with a spread of 20 feet. It has a low canopy with a typical clearance of 4 feet from the ground, and is suitable for planting under power lines. It grows at a medium rate, and under ideal conditions can be expected to live for 40 years or more.

This tree does best in full sun to partial shade. 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.

The Autumn Brilliance Serviceberry’s name may be a mouthful—and even more so is that of its binomial classification, Amelanchier x Grandiflora “Autumn Brilliance”—but this tiny tree harbors enough beauty, strength, and pluck to reinforce its pretty title. This species emerged as a hybrid concocted from the pairing of Amelanchier Canadensis (the Shadblow Serviceberry) and Amelanchier Laevis (the Allegheny Serviceberry), emerging as a multi-stemmed shrub that can alternatively be pruned and cultivated to become a small tree. It suckers less than those two predecessor plants, displays a greater tolerance towards less mild temperatures, and can adapt to a variety of soil conditions. The Autumn Brilliance Serviceberry also has a greater resistance against diseases and conditions such as leaf spot, though it can be susceptible to fire blight and mildew.

This deciduous member of the Rosaceae family has a 4-9 hardiness zone rating and grows best in full sun to partial shade, thriving in the medium, well-drained soils of America’s uplands. This specimen is a bit more compact than other serviceberry species, its rounded canopy scraping up to 15-25 ft. with a respective 15-25 ft. spread. Given its ornamental value and very aesthetic structure, the Autumn Brilliance Serviceberry is a prevalent choice for gardens, lawns, parking lots, roadside buffer strips, street sides, and patios, flourishing throughout all but the southernmost fringes of the United States.

The Autumn Brilliance Serviceberry’s ash-gray bark is delicate, smooth, and malleable; these attributes mean that its trunk can be easily damaged by impact, yet it also enables the tree to be trained to grow with one or multiple trunks. It requires minimal pruning to retain its sturdy upright structure. Yet this species is noted most for its lovely flowers and foliage. It produces lavish clusters of snow-white blossoms in April, emitting a faint and wonderful perfume which attracts a rich variety of pollinators. These flowers are later replaced by the tree’s tiny purple-black fruits, which are often used in jellies, jams, and other desserts. For most of the year, the Autumn Brilliance Serviceberry is also adorned with a lush canopy of dark green leaves, which, true to its name, transform into a brilliant autumnal canvas of fiery brushstrokes with colors ranging from orange and copper to burgundy.
