Borealis was reliesed at University of Saskatchewan( Canada) in 2007.The cross is between Blue Velvet ( Kiev#8) and Tomichka ( F1 of "Delfin" that is F1 of Turchaninowi wild honeyberry from Primorskii kraii, Russian Far East) gave a good result. Some good varieties were developed. And Borealis is one of them but it has a better size and nicer taste and flavour. It was chosen as the best tasting of 43 varieties in Japan. The University recomends the variety for  U-pick operations and for home gardening. The skin of the berries is not firm enough for commercial harvesting and sorting. Hight is about 6ft and estimated yield is 10 pounds+ in colder hardiness zones. 5 inch Size. Tissue Cultured. Zone 2-5. Because of similar genetics Tundra does not pollinate well with Borealis. You can pollinate it with Night Mist or Midnight Blue. WILL BE AVAILABLE is spring!
