Blue balloon flower suddenly has white flowers where I planted seeds from mother plant. I carefully collected seed pods from mother plant and planted the seeds nearby. The new plants have blue flowers and just a few white ones. I am wondering where these white flowers suddenly come from. There are no balloon flower plants nearby.
The plant you collected the seeds from was likely a hybrid. The seeds may not be the same as the mother plant.

My two 6-yr old blue balloon flower plants are full of buds but have not bloomed since spring this year. Is there anything I can do to make them bloom? Also, when is a good time to transplant them? They are crowded by lantana. Any suggestions for transplanting?
The soil could be lacking phosphorus, which is needed for blooming. You can try a phosphorus-rich fertilizer or adding bone meal to the soil. As for moving them, this would be difficult. They typically do not like to be disturbed. However, you can always give it a try once summer begins winding down. Just in case though, I would take some cuttings to root for next season as well.
Deadheaded my balloon flowers. Will plants rebloom? Also, many different opinions on how to plant seeds: 1 - take seeds out of pods and let dry 2 - leave pods intact and spread over soil, top w/light soil in spring 3 - never transplant? Which is correct or are they all wrong?
For the best germination, take the seeds out of the pods. You can wait till the pods are dry to take the seeds out. They can be planted in the house and transplanted later, but remember that they need light to germinate so should be just placed on top of the soil and not buried in the soil.
My self-seeded Balloon flowers this year have all fallen down flat while flowering, and I was wondering if this was because the seeds germinated sitting on the top of the soil and not planted deep enough to help withstand its own weight. However, I see in your notes about propagating from seed to sprinkle the seeds on top. Can you tell me why they are not withstanding their own weight? I'm talking about all of the 10 plants I have.
This is a common issue with Balloon Flowering plants.
Dwarf varieties have less of a 'flopping' issue and taller varieties can be held up with support circles or even staking them.
Cutting the plants down midsummer can help keep the height in check and also encourage more blooms.

What do very young balloon plant seedlings look like? I bought double petaled balloon plants. What do the very young seedlings look like just coming up?

I received some balloon flowers. The roots look like Genseng. Can these be planted in planters and, if so, what size planter should I use?
Balloon Flowers generally don't like to be divided or transplanted, they can be finicky.
You can plant them in pots or window boxes and a depth of 6 to 12 inches would be fine.
Here is a link with more care information.

I must move this plant to a new location. I see that it is best left undisturbed, however. What tips can you give me to move this plant? How deep is the root system? If I dig deep enough and wide enough, will the move be successful?
Balloon Flowers have a long tap root, they will not do well in transplant.
For the best chance for success, move your plant in early spring.
Dig down as deeply as you can without disturbing the tap root and leave all the soil intact.
Move the plant to its new location right away.
