Reflection Riding and Arboretum is one of the most beautiful places in the Chattanooga area and yet many people have never been there. The people who know it go there to get away from urban life for a spell, but at this time of year many local gardeners head for the Arboretum for the semi-annual native plant sale. Over 12000 plants representing over 100 different species are for sale beginning this Friday September 12th. I went over to the Arboretum last week to talk to Dr. Paola Zannini Craddock who, along with a crew of volunteers, was busily preparing for the sale.
