What is Juniper?
The genus Juniperus includes 60 to 70 species of scented evergreens native to northern Europe, Asia, and North America. The plants bear blue or reddish fruit variously described as berries or berry-like cones. Junipers are widely used as ornamental trees. The cone is a small, green berry during its first year of growth that turns blue-black during the second year. Small flowers bloom from May to June.
