Crop Profile

Honeyberries, Lonicera caerulea, are a relatively new crop to North America that go by many different names, including haskaps, blue honeysuckle, and sweet berry honeysuckles. The people of the island of Hokkaido in Japan have a history of eating honeyberries going back hundreds of years. They are a member of the honeysuckle family native to the boreal forests of Russia, Japan, North America, and the Kuril Islands. Honeyberries from each of these regions have been classified as separate subspecies with distinct differences in traits such as productivity, time to maturity, uniformity of ripening, and tendency to drop their berries when ripe.
Honeyberries are an irregular-shaped, elongated, blue berry that grow on bushes. Plants are extremely cold hardy and can be grown in USDA zones 1-8. They are easy to manage, growing 3-6′ tall with no suckering or thorns. Minimal pruning is needed. Unlike blueberries, plants tolerate of a wide range of soil pH, from 5.5-8. The earliest maturing varieties ripen in June, two weeks before strawberries. Flowers appear six weeks before the last frost and are hardy down to at least 20F. Varieties require a compatible pollinizer with an overlapping bloom time in close proximity. Plants will begin bearing a few fruit in years one and two, but three to four years are required for large quantities. Plant and fruit characteristics will vary depending on the variety.
Honeyberries have a flavor described as a cross between a blueberry and a raspberry with an added zing. They can be eaten fresh or used in processed products such as pastries, jams, juice, wine, ice cream, yogurt, sauces, syrup and candies. The skin is thin and dissolves quickly. Seeds are tiny, much like a kiwi. Honeyberries make a high quality wine with a deep burgundy color. The nutritional profile of honeyberries are outstanding. The berries are higher in antioxidants and Vitamin C than blueberries.
Honeyberries are remarkably free of pests and diseases. Because they set fruit so early, insect pests rarely affect production. Deer may browse younger plants but leave older wood alone. Birds, especially cedar waxwings, pose the greatest threat and bird netting is recommended. Powdery mildew can affect leaves in mid-summer, after harvest, but does not seem to affect long term plant health. Susceptibility varies significantly between varieties.
