Which wood for my garden arbor or pergola?

The choice of wood is often the major choice for a garden arbor, pergola or gazebo.  Design is the main factor for many consumers, but for manufactures, they will usually only use one kind of wood.  So, where doe it shake out?  It shakes out with consumers being led to certain designs by the choice of wood, or being led to the choice of wood by the design that they like.  The typical choices are white cedar, red cedar, treated pine and more recently shorea, bangkirai and eucalyptus.
