In an ongoing effort to improve the educational quality of exhibits at The Newport Flower Show, a Photo Key Card is required for all exhibits containing three or more rooted plants. A photo key card is a photo of your exhibit attached (or printed) on white card stock no larger than 5” x 8”. A numbered list of botanical and common names refers to the corresponding numbered plant in the photo. Please make an effort to complete your Photo Key Card prior to visiting the Passing Tent. For protection from the elements your Photo Key Card and Entry Card will be laminated to 8 ½” x 11” cardstock. Please do not use photo paper, which will blur in the laminating process.
