  1. I am not sure, but I think I may have a Barking Tree Frog in my potted Lemon Grass. I am in Hazlehurst, MS. My Lemon Grass is in one of those 1/2 barrel wooden pots and Prince Charming seems quite content, sitting comfortably on a blade that is about 1/2″ wide. He’s about 3/4 inch long. I like having him hanging around. What will happen to him in the winter? Where will he go? How long will he liver? What can I do to encourage his return?

      1. Thanks much for the reply. I put a shallow dish of filtered water out last night. Could not find him this morning. Alas, mine may have been a layover destination!
