I feel this is likely the ID of the GIANT grape vines in full flower I noticed thriving at the edge of the swamp between Dad's nursing home/rehab center and Raulerson Hospital there in Okeechobee. The size and structure of the bloom clusters made me feel it will bear small clusters of small grapes, much smaller than my "Gray Street Grape" now laden with thousands of large green grapes. I'll be sure to check this grape each time I visit Dad
