Survives zone 4 through 9

Harvest calendar

Best planted in early spring after your last frost, or in fall before the ground freezes, depending on your climate.

Amelanchier arborea is the tallest and most tree-like of the widespread North American serviceberries, capable of reaching 12m (40ft) in the wild though usually seen as a large multi-stemmed shrub or small single-trunk tree in cultivation — it produces some of the earliest white blossom of the eastern forest understory, opening before the leaves emerge in early spring.

Mature size

Small tree 6–12 m, occasionally to 20 m in the wild — the largest serviceberry, and the one the name arborea records

Environment

Woodland

Native range

Eastern North America, from New Brunswick south to Florida and west to Minnesota, Texas, and eastern Oklahoma — the most widespread of the eastern tree-form serviceberries, occurring across a broad range of upland woodland habitats.

Status

Both wild and cultivated

Years to fruit

2–4 yrs

Growth speed

Moderate — about 23-38 cm/year (9-15 in) under good conditions, reaching typical landscape size of 4.5-7.5m over roughly 5-8 years.

Spacing

400 cm (157 in) apart — about 16 m² (172 sq ft) per plant

Leaf shape

Finely toothed, obovate leaves that emerge covered in silvery down (giving rise to the "downy" common name) before maturing to smooth dark green, with strong fall color in shades of orange to red.

Root system

Tends toward a taprooted, single-trunk habit in the wild but suckers readily from the root crown in cultivation, requiring removal of suckers to maintain a tree form rather than a shrub clump.

Fruit description

Small berries to about 10mm across, with quality varying considerably between individual plants — some are dry and nearly tasteless while others are sweet and juicy — ripening unevenly over 2-3 weeks in early summer; edible raw, cooked, or dried.

Propagation

Seed is best harvested green and sown at once; stored seed needs about 4 weeks of warm stratification followed by winter cold before it will germinate the following spring, and can otherwise take up to 18 months. Also propagated by layering (about 18 months to root), division of 2-year-old root suckers, softwood cuttings, or — for named cultivars — grafting.

Pollination

Documented to hybridize with A. bartramiana, A. canadensis, A. humilis, and A. laevis where their ranges overlap — a reflection of the genus-wide tendency toward hybrid swarms among polyploid apomicts, which can make individual wild plants hard to key to a single species.
