I have a balloon plant (Platycodon) in a rail box. This is my first balloon plant and I don't know what to expect for the change of seasons. The plant was flowering like crazy in June and July. . .then slowed down to almost nothing in August. Just this week it started changing color and the entire plant is yellow. Is it dying on me. . . or is it going into fall?
This perennial plant flowers from summer to early fall, with heaviest flowering coming in mid to late summer. The cold hardy plant can be grown in sun or partial shade and in moist, but well-draining, soil. This is important. Balloon plants need a lot of moisture and it is possible that yours have become too dry. Pinch back dead blooms and apply mulch for winter protection. Watering should be cut back during winter.

There are so many tiny blooms. I have read information that indicates it will continue to bloom if you deadhead them. When you deadhead them, do you cut off the end of th stem or just each individual little flower stem?

Why balloon flowers won't open.
Good question, wish I had an easy answer! Are you fertilizing? Are you deadheading? I'm attaching this haricle, hopefully it will help: https://www.gardeningknowhow.com/ornamental/flowers/canterbury-bells/canterbury-bells-plant-how-to-grow-canterbury-bells.htm

My balloon flower has come back in spring for several years, but this year I don't see it.
Balloon flowers typically sprout from the soil in late spring, so I would give it a little more time. Also, plants can be slow to awaken after a cold harsh winter.

Trying to plant from tallest to shortest.
The answer to your question really hinges on the variety you have - different varieties differ in plant size. According to Cornell University, the height of balloon flowers is 2.5 to 3.5 feet with some dwarf varieties reaching just 6 inches tall.
