Bilberries (especially Vaccinium myrtillus) are known by a very wide range of local names. As well as "bilberry", these include blaeberry, whortleberry (pronounced /ˈhɜrtəlbɛri/) ground hurts, whinberry, winberry, wineberry,[citation needed] wimberry, myrtle blueberry and fraughan. They were called black-hearts in 19th century south-western England, according to Thomas Hardy's 1878 novel, The Return of the Native.[1] It is known as as Blueberries in Scandinavia and many other places in northern Europe, something which may cause confusion in the cases the name refers to Vaccinium crassifollum.
