Can I start a passion flower vine from the bulbs produced by the vine? If I can, how do I do that? Does the bulb need to be green or in a dried state? Do I plant the actual bulb or the seeds inside the bulb? I am wanting to get the bulbs from KY and plant in FL.

How do I prune a 16 ft Passion Fruit plant in order to bring it indoors on Vancouver Island B. C. ? Our temps can get below freezing at times.
While these plants will normally die down for winter dormancy, thus, not requiring too much pruning, since yours is quite large, cutting it back by about a third (or even half, if not more) might make it easier to fit the plant inside. Here is an article or two on overwintering passion flowers that you may find helpful: https://www.gardeningknowhow.com/ornamental/vines/passion-flower/preparing-a-passion-flower-vine-for-winter.htm

I have a passion flower in a pot. Can it be overwintered outside in the pot? If it is in the ground, can it be overwintered outside? I am in Zone 5 but it overlaps into 6. I am hearing different stories.
It really just depends, which is probably why you are hearing conflicting stories. First, it depends on the variety you are growing. A standard passion flower can winter in Zone 6 in the ground, but many of the fancier varieties need Zone 7.
Second, because yours is in a pot, you should be aware that you should treat plants in pots as though they need to survive one zone lower than your current zone. This is due to the fact that containers lack the insulation that plants in the ground have. You can combat this somewhat by placing the container near foundations and mulching, but it is still going to be more susceptible to temperature fluctuations than plants in the ground.
Third, is when you are in a border area, you never know what winter might throw at you. You may have several Zone 6 winters and the plant would be fine and then get hit with a Zone 5 winter, which would kill the plant.
Do you have an attached garage or basement that you could store the container in? This would be your best bet for getting the passion flower to make it through the winter.

Planted my passion flowering vine on the southwest side of my house. It did not bloom at all. Kept looking for the beautiful purple flowers. I also have a vine on the east side of the house. It grew like crazy but no flowers showed up on both vines. Why?
It sounds like it may have too much nitrogen and not enough phosphorous. Plants need a balance between phosphorous and nitrogen to bloom well. I would recommend giving it some bone meal to increase phosphorous.
I live in NW Missouri. I planted a passion flower that has done very well. The fruit it produced was hollow. Nothing inside. What happened?
Depending on your circumstances (container or garden plant), here is an article or two that you may find helpful: https://www.gardeningknowhow.com/ornamental/vines/passion-flower/passion-flower-winter-care.htm

As to your question regarding hollow fruits...this is oftentimes a result of the species (of which there are many). Some species only produce hollow fruits while others produce fruit with edible seeds and some pulp inside. Apparently, you have one of the hollow-producing fruit varieties.
I noticed that the article on passion flowers said to bring them in and leave them in a cool, dark place. If I cut it back and bring it in the basement of my home where it's cool and dark, do I still need to water it regularly or maybe just when the soil is dry? I bought one of these plants this year and it's beautiful. I would hate to loose it. I live in Niagara, NY so outside is out of the question.
You will want to water it about once a month when it is dormancy. It needs very little water in dormancy but it does need a little.
