Volunteer sunflower!
I wish my four o'clocks would bloom as well... but I did a soil test last weekend and found out that everything is dreadfully deficient in all nutrients, so I've been giving lots of extra plant food and hopefully it will help. If nothing else, I haven't seen end rot on the tomatoes any more (although none of them are quite ripe yet).
I'm starting to get bell peppers to eat, though!
Delicious bell pepper.
