Amelanchier canadensisThe delightful Serviceberry tree, Amelanchier canadensis, thrives best in very well drained to boggy and damp conditions where it will grow into a small tree or large shrub. It offers an enchanting, pretty display of lovely star shaped white flowers in spring, March to April. The flowers have a slight but not significant fragrance. The flowers give way to green, small and round berries which ripen to red and mature to a dark purple black at the start
