Blueberries first came to Europe in the 1930s from North America. Comprising a range of lowbush and highbush varieties, the more common commercially grown plants can reach 4-10 feet tall and up to 5 feet across.
A perennial flowering bush, blueberries belong to the ‘Vaccinium’ genus which also includes cranberries, bilberries, grouseberries, huckleberries and whortleberries.
The flowers are bell-shaped and generally coloured white, pink or red with the main bushes being deciduous. Leaves are 1-8cm long and 0.5-3.5com wide depending on the variety. Flowers appear in April and give way to berries frim late May to early June which gradually ripen from pale green, to red and finally purple.
