The spathe on your plant is distinct (open from end to end) so that rules out everything except Commelina communis, C. dianthifolia, C. caroliniana, and C. diffusa. The closest record of C. dianthifolia to you is in West Texas. The spathe is the wrong color and the flower is the wrong color and structure for C. communis, which leaves only C. caroliniana and C. diffusa. The closest C. caroliniana is recorded to you is Baldwin County. Although C. diffusa is not recorded in your county, it is recorded in every county surrounding you including those in Florida, so it is likely in your county also. The only thing I can positively see that makes me think it is C. diffusa is the spathe shape. Flora of North America say the the spathe of C. caroliniana is "not at all to slightly falcate" (sickle shaped), C. diffusa is "usually distinctly falcate". Yours to me appears to be distinctly falcate.
