Amelanchier x grandiflora ‘Autumn Brilliance’ (Serviceberry) is an exceptional deciduous shrub or small tree. It’s prized for its multi-season interest, from delicate blossoms in spring to vibrant foliage in fall.

Autumn Brilliance Serviceberry: An In-depth Look

Native: This plant is a hybrid of the native North American species, Amelanchier arborea and Amelanchier laevis, primarily from the eastern U.S. and Canada.

Plant Type and Habit: Autumn Brilliance Serviceberry is a deciduous shrub or small tree with an upright, spreading habit and a rounded canopy.

Size: Typically, ‘Autumn Brilliance’ reaches a height of 15-25 feet (4.5 to 7.5 meters) and a similar spread, making it versatile for various landscape settings.

Flowers: In early to mid-spring, the tree is adorned with clusters of star-shaped, white flowers. The flowers are larger than those of other serviceberries. These blossoms are both delicate and showy, providing a gentle contrast to the awakening landscape.

Fruits: Following the flowers, it produces small, round berries that transition from red to deep purple as they mature. These fruits are not only ornamental but also edible, bearing a sweet flavor.

Foliage: Oval leaves emerge with a bronze tint in spring, maturing to a deep green in summer. Come autumn, as the name ‘Autumn Brilliance’ suggests, the foliage transforms into fiery shades of red and orange.

Bark: The bark is smooth and gray, adding a touch of winter interest with its subtle sheen.

Hardiness: Autumn Brilliance’ is hardy in USDA zones 3-9, making it resilient across a broad swath of climates.

Uses: Given its size and ornamental features, it’s ideal as a specimen tree in small gardens, a hedge, or screen. It’s also used in wildlife gardens, thanks to its appealing berries.

Wildlife: The fruits attract various birds, making it a haven for ornithologists and nature lovers. Plus, bees and butterflies are drawn to its spring blossoms.

Deer and Rabbits: While no plant is entirely deer or rabbit-proof, serviceberries aren’t their first choice, giving it a moderate resistance.

Drought: Once established, the ‘Autumn Brilliance’ has some drought resistance, though regular watering in prolonged dry spells is beneficial.

Toxicity: Serviceberries are non-toxic to humans and pets. In fact, the berries are quite tasty and can be used in jams and pies.

Invasiveness: Being a cultivar of a native species, it doesn’t pose an invasiveness risk in North American landscapes.

Benefits: Beyond its ornamental value, it offers edible fruits, supports local wildlife, and enhances biodiversity. Its adaptability to various soils and resistance to common pests adds to its benefits.

How to Grow and Care for Autumn Brilliance Serviceberry

Light: Prefers full sun to partial shade for optimal growth and flowering. Best berry production and fall color occur in full sun.

Soil: Thrives in well-draining soil but is adaptable to various soil types. Slightly acidic to neutral pH is ideal.

Water: Water regularly after planting. Once established, moderate watering is needed, but ensure consistent moisture, especially in dry periods.

Fertilizer: Apply a general-purpose fertilizer in early spring before new growth starts.

Pruning: Best pruned after flowering to maintain shape and remove dead or diseased branches.

Propagation: Propagate by layering or by semi-ripe cuttings in summer

Pests and Diseases: Generally resistant to most pests and diseases. This cultivar supposedly resists leaf spot. Watch for aphids, spider mites, rust, fire blight, powdery mildew, and honey fungus.
