Blueberry: Known as the High Bush American Blueberry, it is the same genus as the low-grown, wild blaeberry, both of which thrive on acidic peaty soil. The blue-black blueberry is larger than the blaeberry and has a powdery blue bloom, greenish to purple flesh and a winey flavour, less tart than a blaeberry. It adds character to fruit pies and is the most popular flavouring for American (blueberry) muffins. It has been made available to growers in Scotland by the Scottish Crop Research Institute, and some growers have taken up the crop. Though they take some time to establish, they can remain cropping for fifty years.
