An evergreen would be the best symbol since it was used by pretty much everyone including the Romans, Huns, Celts, Babylonians, Sumarians, Persians, Assyrians, Eggies, Greeks.... etc.

It was pretty much one of the most wide spread pagan symbols of rebirth which was even fused into a Christianity as the Christmas Tree among other things. I rather have a evergreen tree to represent Pagans rather than the stupid pentagram.
