Blaeberry? I love it when you speak with that Scottish accent. :-) The proper name for these is Bilberry and maybe even the Northern Bilberry, but that hybridises with the first one anyway. Other names are Blueberry or Whortleberry, depending on where you come from. Scottish people call them Blaeberry, which is just their accent and way of talking.
Latin Name: Vaccinium Myrtillus.
The Black fruit is edible and quite nice, but you need a lot to make a pie!!
