The annual luncheon, now in its fourth year, is a fundraiser for the Knoxville Botanical Garden and Arboretum and features the new spring collection of designer hats by milliner Patricia Frankum. Mimosas will be served, followed by a seated lunch by Rex Bradford Jones of Bradford Catered Events. Attire is garden chic with hats encouraged. The event will take place in the new Welcome Center.
