Serbian Spruce (Picea omorika) – Serbian spruce is native to a small region of limestone mountains along the upper Drina river of Bosnia and Serbia, in Southeastern Europe. The Serbian spruce grows to a height of 50–60' and a spread of 20–25' at maturity, growing at a slow to medium rate, with height increases of anywhere from less than 12" to 24" per year. The Serbian spruce grows in acidic, loamy, moist, rich, sandy, well-drained and clay soils. Full sun and partial shade are best for this tree. Outside its native range, Serbian spruce is of major importance as an ornamental tree . It is also grown to a small extent in forestry for Christmas trees, timber and paper production.
