I have one in a 2x2x2 ft planter. After a couple of years this plants is covering over 16 feet of fence.
Reply:You will need a few morning glories to cover your balcony, they need a trellis to hang onto I would say the two gallon size pot would do. Or one of the oblong planters

You could mix them with Moon flowers to have blooms and fragrance at night
