Amelanchier alnifolia, commonly known as Saskatoon berry, Pacific serviceberry, western serviceberry, alder-leaf shadbush, dwarf shadbush, chuckley pear, or western juneberry, is a deciduous shrub or small tree native to western North America, particularly found in open woodlands, forest edges, and riparian areas. It typically grows to 1–8 meters in height and has a growth form that can vary from suckering and forming colonies to a clumped structure. The white flowers bloom in early spring and are followed by purple, berry-like pomes that are both edible and attractive to wildlife. The plant is valued for its multi-season interest, with showy white flowers, edible fruit, and vibrant yellow to red fall foliage.

Amelanchier alnifolia is a versatile plant used in urban planting, border planting, and as a naturalized hedge. It is also popular for its edible fruit, which can be used in jams, jellies, and pies. The shrub thrives in full sun to part shade and requires medium amounts of water. It is adaptable to various soil types, except for poorly drained or heavy clay soils lacking organic matter. Avoid shallow soils, particularly where the water table is high or erratic. While it has exceptional winter hardiness, late frosts can damage blooms. It is important to provide ample sunlight for fruit ripening. Gardeners should be aware that the plant can spread through suckering, potentially becoming invasive in some areas.CC BY-SA 4.0
