They look like a mad scientist's idea of a blueberry.
Yes, the deep purple-blue color is there, but instead of the familiar orb-like shape, the profile is more elongated; think capsule, or lozenge, or teardrop.
Still, the honeyberry has all the juiciness — and the burst of sweet-tart zinginess — of a just-picked blueberry.
"It's a combination of a wild blueberry meets a raspberry meets a blackberry," said farmer Jason Amundsen. "It's magical."
He would know. Amundsen has 10 acres of honeyberry bushes under cultivation at his farm in Wrenshall, Minn., about 30 miles southwest of Duluth, and he's banking on the honeyberry becoming local agriculture's Next Big Thing.
Why not? The plant is both fast-growing and extremely hardy, with origins in Siberia and Japan's northernmost island, Hokkaido.
"Nothing matches those climate conditions better than Duluth," said Amundsen with a laugh.
Enduring a Minnesota winter isn't the honeyberry's only virtue.
