Tundra from Canada, Berry Blue from Oregon
The Best, the Worst, and the Average Tundra haskap
Tundra and Borealis are closely related and virtually indistinguisable to the untrained eye, but once they bear fruit the Borealis will have larger berries.
I was delighted to hear of a couple of instances of honeyberries being grown in Minnesota. Here is a picture of a three year old Berry Blue, taken in late August of 2010 at Bergeson Nursery at Fertile, MN. The well developed shrub was already entering dormancy. Berry Blues grow up to 8 feet tall, while Tundra and Borealis peak at 6 feet.
