Like most parviflora's, this dwarf pine has become very popular. 'Arnold Arboretum' has a sturdy, densely conical habit and its branches are thickly covered in medium length, blue-green needles. The new foliage is a lighter green, giving this small tree a refreshing burst of energy. It receives its 'miniature' classification because a ten-year-old tree is only three feet tall and under two feet wide. 'Arnold Arboretum' is a beautiful and interesting addition to any landscape.
