Jackson, MO(Zone 6b)

I'm in zone 6 with heat and humidity in the summer.
1. Should lobelia be grown in shade?
2. Does it re-seed well?
I am debating on planting Lobelia or Campanula.
They both seem to like cool weather. I am wanting a blue flower and a white flower that is a low prostrate or trailing plant.
I could not find much information about Lobelia.
Any tips for growing either of these two plants?
