Dig, here is a picture of my Moulin Rouge in a 16 in pot. It grows only 4 to 5 ft, so I think it is perfect for a larger pot. Looks like I may have had 3 plants in this pot.

I had it in with various small flowers, I think nictotina and alyssum. Since sunflowers have phytotoxins which inhibit the growth of other plants the other small flowers did not fair well.
Now I just keep the pot in the back of several other pots so the taller sunflowers act as a backdrop and don't plant anything on the bottom. Once the potato vine in the other pots get large enough, I try to make them cover at least part of the sunflower pot. ;o)
