Juniper (Juniperus communis)
Overview
Juniper (Juniperus communis) is a coniferous shrub or small tree that may reach about 49 ft (15 m). It bears needle-like leaves, male and female flowers, and spherical blue-black “berries” (actually seed cones) rich in potent volatile oils. Juniper berries have been used for centuries as a flavoring (notably in gin) and for their antiseptic, diuretic properties.
