Vaccinium ovalifolium

Vaccinium ovalifolium (commonly known as Alaska blueberry, early blueberry, oval-leaf bilberry, oval-leaf blueberry, and oval-leaf huckleberry) is a plant in the heath family with three varieties, all of which grow in northerly regions (e.g. the subarctic).

Growth


V. ovalifolium is a spreading shrub which may grow to 5 ft tall. It has pink, 1/4 in, urn-shaped flowers. Berries are dark blue, often black, sometimes with a waxy coating. Cytology is 2n = 24, 72.

Distribution
The original variety (i.e. the automatically named V. o. var. ovalifolium) is found on both the eastern and western sides of the Pacific Ocean. In North America, it is distributed throughout Canada (Alberta, British Columbia, Newfoundland, Nova Scotia, southern Ontario, southeast Quebec, and southern Yukon) and the United States (southern Alaska, Idaho, northern Michigan, Oregon, western South Dakota, and Washington). In Asia, it is distributed throughout Russia (Kamchatka, the southern Kuril Islands, Primorsky Krai, and Sakhalin) and Japan (Hokkaido and central and northern Honshu).

The two other varieties are confined to Japan and Russia:


 * V. o. var. sachalinense is only found in Sakhalin in Russia, and Hokkaido in Japan.
 * V. o. var. alpinum is distributed only within the Daisetsu and Hidaka Mountains, both on the island of Hokkaido.

Uses
V. ovalifolium is used in jams and jellies and for making liqueur. Blueberry herbal tea can be made from the leaves, or from the juice of the blueberries themselves.

V. ovalifolium has been used in Russia in the making of dyes, including the use of its tannin.

In the winter, V. ovalifolium is an important food source for grazing deer, goats, and elk, and in the summer the nectar feeds hummingbirds.
