Our home in Vermont has a rustic natural feel, so I like to bring in elements like pine cones and berries when putting together the outdoor urns and such.

I usually just go into the surrounding woods and trim pine branches of various types and yews as well with their lighter green and more delicate texture.  There are endless possibilities when using natural materials.  Here I also used tall branches for extra height.  Look for birch branches with their beautiful white papery bark.
