small branched shrub found mainly in moors, humus rich- soil and open woods from low-lands to mountains, Bilberry (vaccinium myrtillus) bears small blue-black, many seeded berries. Also commonly known as whortleberry, Bilberry has been a source of fresh jam for hundreds of years. Extensively written about in 16th century herbals, this berry is native to northern Europe and Asia; with its nearest American counterpart being the huckleberry. During Word War II, Royal air force pilots swore that eating Bilberry jam prior to night missions significantly improved their visual acuity in the darkness.
