The flavor of the well-ripened fruit...Read More has been compared with raspberries and blueberries.

This species is not self-fertile and needs at least two different compatible cultivars in order to set fruit.

Grows and fruits well in Z1--Z4. In Z5-6, you may be better off with Japanese cultivars, as Russian material (from which 'Borealis' was bred) will break dormancy during winter thaws. The southern limits of this species have not been well explored, but for good fruiting, cool summers are necessary.

Fruit turns blue several weeks before it's fully ripe--the interior of fully ripened fruit is deep purple-red. Unripe fruit is bitter. Fruits will be harvested by the birds unless protected by netting.

Also called honeyberry or sweetberry honeysuckle.

According to Wikipedia, it can grow in soils with pH 3.9-7.7 (optimum 5.5-6.5).
