I use this tree/bush as a potted evergreen for some winter interest on the patio area. It has been trained from a bush into a tree with top pruning every other year to keep an open sculptural form. Had read that they don't like root pruning. In our area some have become trees approximately 20 feet in height and width. Originates in south and central Europe. Have small pine cones approximately 1-2 inches in diameter.
