Survives zone 3 through 8

Harvest calendar

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

Amelanchier canadensis is a wetland-adapted, strongly colony-forming shrub of the Atlantic coastal plain, distinct from the more upland, tree-form A. arborea and A. laevis it is frequently confused with in the nursery trade — its vigorous suckering habit makes it especially useful for naturalizing along pond and stream margins.

Habit

Shrub

Edible part

Fruit

Ripens

Summer–autumn

Mature size

Multi-stemmed shrub 3–6 m, suckering into a dense upright clump

Light

Partial to full sun — survives in shade, flowers/fruits poorly there

Soil pH

6.0–7.0 (near-neutral)

Environment

Wetland

Native range

Eastern North America, concentrated on the Atlantic coastal plain from Newfoundland and Nova Scotia south to Georgia and the Gulf states, generally within about 200 miles of the coast and rarely above 200m elevation — it favors wet, often acidic sites such as pocosins, bogs, wet pine flatwoods, and maritime forest margins.

Status

Both wild and cultivated

Years to fruit

2–4 yrs

Growth speed

Moderate, roughly 30-60 cm/year (1-2 ft), reaching mature size of 4.5-6m in about 10-20 years.

Spacing

350 cm (138 in) apart — about 12 m² (132 sq ft) per plant

Leaf shape

Simple, oblong leaves 2.5-7.5cm long and under 2.5cm wide, serrate-margined with a rounded base and a small sharp tip; new growth is finely hairy, maturing to smooth medium-to-dark green above with persistent fine hairs beneath, turning showy orange-red in fall.

Root system

Multi-stemmed and colony-forming, spreading by root suckers from the crown rather than staying a single clump — this suckering habit is more pronounced than in the more tree-like A. arborea and A. laevis.

Fruit description

Berries about 10mm across (up to 12mm in good forms) with a sweet flavor carrying a hint of apple, though quality varies between plants and some individuals are noticeably more astringent; cooked seeds add an almond-like note.

Propagation

Rooted from hardwood cuttings taken in early spring or softwood cuttings taken in summer; seed can be sown untreated in fall or cold-moist stratified for 90-120 days before spring sowing (best results come from collecting seed green and sowing it immediately). Colony-forming root suckers can also be divided and transplanted.

Pollination

Hybridizes freely with other Amelanchier species where ranges overlap, consistent with the genus's polyploid apomictic complexes — this can blur species boundaries in the wild and means seedling offspring don't always resemble the parent plant.
