    Passiflora lutea, Passiflora incarnata, and Passiflora foetida and others are all attractive to Gulf Fritillary butterflies. Passiflora incarnata is probably the most common in gardens and has large purple flowers. If that's not the one- there are over 200 passion flower species, but the flower colors and appearances can help you find the one you had.

    No, they will not survive. It would be best to put the plants in container, and bring them in to continue growing in a brightly lit window over the winter. Here is more information: https://www.gardeningknowhow.com/ornamental/vines/passion-flower/passion-flower-winter-care.htm

    Depending on your climate zone, this can be completely normal as it goes dormant for the winter. Otherwise, breaking the tendrils that it uses to climb can cause this as well. There are many factors that could have contributed to this. If there is any more information that you can offer it would help me to help you better.

    There are, actually, a few different methods for trimming these depending on the age of the plant. Dormancy is always a safe time if you are unsure.

    The most common causes for this are: Not enought light, not enough water, or a lack of potassium and phosphorus in the soil. This link will take you to a set of articles that will help: https://www.gardeningknowhow.com/ornamental/vines/passion-flower/

    Because you mentioned that you have self-seeding tomatoes near your passion vines I would have suspected a problem with Root Knot Nematodes (something to which passion vines as well as tomatoes are highly susceptible), but, without seeing a photo of the vine, I cannot be sure about that. But you definitely should contact your local Cooperative Extension for assistance in getting a diagnosis. Most cooperative extension services are free (or will help you for a minimal cost if a specimen needs to be sent to their university labs).
