Paul We grow sunflower with our yard-long beans in North Louisiana to redirect stink bugs .... they grow well together here as the soil does not need anything different ... Marigolds grow well to help with the horn worms ....

Read the notes here about when to plant, how long it takes from planting to harvest. Probably can grow in most places. Animals if hungry will probably eat them. How big the flower grows will depend on how well the plant grows to some extent.( And the variety) If first attempt at growing you probably have little chance at producing flowers on a certain date.
