5 Saskatoon serviceberry
AMELANCHIER ALNIFOLIA, ZONES 3 TO 8
The Saskatoon serviceberry is an ornamental shrub that produces white flowers in spring and purple-black berries in early summer. This plant usually grows 3 to 8 feet tall and requires full sun or light shade.
Why we love it: The berries are tasty in pies and muffins—if you can beat the robins to them.
