Thanks Bee,
Malabar Spinach or Pole Beans might be good to grow amongst the tomatoes - if you have lots of space! I tried growing beans with the tommies one year (sharing the tall trellis) but it got a bit crowded.
Honeysuckle does well in Ontario, but is a perennial that would be too big for my planter.
I think I will try Thunbergia, and the white would would look great for me
