If you're keen on attending flower shows, consider taking a day trip to Tulbagh (map) to see the Tulbagh Horse and Wildflower Show from 22 to 25 September. The show comprises the National Horse Championships along with the natural wildflower exhibition and will more than certainly have food stalls, a beer garden and plenty of arts and crafts stalls.
