The 15' Green Belgium Artificial Christmas Tree with 3100 White Light is an extensive tree line that comes in many heights and diameters. The entire Belgium family will have a lush and beautiful mixture of 3 needle types. 2 PVC needles with a third needle made of bristol pine. Of the 2 PVC needles, one looks like a Frasier fur needle, and the other looks like a balsam needle. The third bristol pine needle gives it that soft full scotch pine look. The three needles combine to give the tree the richness that your home deserves.
