SASKATOON ‘NORTHLINE’
What is it? ‘Northline’ is a cultivar of Amelanchier alnifolia, a pretty, multistemmed suckering shrub native to North America that reaches H2.5-3.5m (8-12ft). In summer it produces sweet, purple, blueberry-like fruit to eat fresh or cooked. Despite appearances, amelanchier belongs to the Rosaceae family, which includes apples, plums and roses. ‘Northline’ is self-fertile and flowers slightly later than some other cultivars. How should I grow it? These are robust, hardy plants, but it’s best to avoid frost pockets to protect the May flowers. They prefer a sunny or part-shaded site on fertile, moist but well-drained soil. Plants will take less than perfect conditions with the exception of very heavy wet ground. How do I look after it? Once plants are established (after four or five years) prune out one or two of the oldest stems each year to encourage additional young shoots. When are they ready? Plants bear fruit from 3 to 5 years old, ripening in June or July hence its nickname, Juneberry. They can be dried as well as used fresh. Where can I buy one?
