This is Beautyberry, Callicarpa americana, in the family Verbenaceae.  It is a native shrub in the southern US, and is often used as an ornamental shrub to attract birds to the garden.  This one is growing out of the sidewalk at the Methodist Church in Blairsville.  It was probably planted by birds or deer.  They love to eat the berries.  

 

When Beautyberry is in bloom, it's not that noticeable.  But, when the berries ripen to this bright purple all along the stems, you can't miss it!  It's in this beautiful stage now, so be on the lookout.  I hope you see some in your travels.  

 

HAPPY GARDENING!!!
