We’re berry excited for this extra delicious plant face-off. 

In this week’s shrub showdown, our hosts go head to head with serviceberries and haskaps. Sean represents the former, a member of the Amelanchier genus also known as saskatoons, juneberries, and shadbushes, among other names. With cocky confidence of a guaranteed win, he extols their hardiness (down to zone 1!), their robust hybridization, and their independence when it comes to fertilization. Who needs a pollenizer? Not serviceberry! Sometimes they don’t even need pollinators. With tangents into breeding seedless fruits and food-as-medicine research, we savour serviceberry’s taste, versatility, abundance, ecosystem benefits, and ability to thrive across North America.

Erin swings in second with haskaps, a relatively new fruit on the commercial block. She tells us about breeding programs in near-polar regions around the world that are crossing varieties from Canada, Russia, and Japan for taste and resilience. While haskaps do need pollenizers to set fruit, Erin argues for their ease of care, their long lives, and their bountiful all-at-once harvests. The conversation delves into humane ways of bird-proofing berry crops, the perils of “superfood” marketing, and the fragility of fruit trees that bloom too soon. Haskap blossoms, by the way, can survive a -7 C frost.
