Wonder Valley Farm preparing to sell local lavender, forest botanicals and honey.

You can hear the excitement in Sierra Cox’s voice when she talks about Wonder Valley Farm. The agritourism startup, located in Gandeeville, Roane County, is co-owned by Cox and her partner John Pennacchio, both Navy veterans who moved across the country to start a 100-acre lavender, bee and forest botanicals farm right here in the Mountain State.
