I'm thinking that this is too many plants for so small a pot, especially because you are in Florida, and you would be having to water at least twice a day in the summer, and the plants would be too crowded. A better option would be the beans in a separate pot, preferably one at least 12 to 16" across and flowers in a pot of their own. . I would not recommend hollyhocks for pots; they get too tall, and could be blown over by the wind. Zinnias are good if they're the shorter kind. Another idea is to go to a garden center if you can, and see what kind of combo pots they are selling. I do combo pots every year; here's mine this year.
These are in very large pots; I still expect to water at least once a day when it gets really hot here.
