Amelanchier alnifolia aka Saskatoon

Amelanchier alnifolia, also known as the saskatoon berry, Pacific serviceberry, western serviceberry, western shadbush, or western juneberry, is a medium to large deciduous shrub or small tree native to North America. It produces edible berry-like fruits that resemble large blueberries. The shrub has bronze-tinged young leaves that turn dark green in summer and orange-red and pink-purple in autumn. In spring, it blooms with self-fertile white flowers. The ripe fruits, about 10mm in diameter, are blue-purple-black and are often consumed by birds and squirrels. They can also be used to make jams and pies. The plant is not very demanding in terms of soil and moisture and can tolerate temporary drought. It is commonly grown for its delicious fruits, which can be used to press juice or make jams and compotes. In Finland, it is also referred to as Irga alder and is used as an ornamental tree. However, it should be noted that Irga alder is not widely spread in Finland and its bushes can become invasive if left to run wild.
