Juniper bushes can be found in eastern Europe, Bulgaria, Hungary, also in western Europe France and Spain and in north America - Canada. This evergreen shrub grows up to 6 metres tall. It has dark green or blue needles and small flowers and berries. The berries change colour over the first few years of growth. They start off green, but after a year or two, they turn black. Juniper is used to flavour food and drink and is the characteristic aroma in gin.
