Title: Plant identification of vine in Tennessee
Answered by: Nan Hampton
Your description of the fruit of the vine sounds like that of the native Passiflora incarnata (Purple passionflower). As it happens, it is the State Flower of Tennessee. You can see more photos of the vine and its fruit on the USDA Plants Database page. If this isn't the vine you are describing, you can do a COMBINATION SEARCH in our Native Plant Database, choosing Tennessee under Select State or Province and "Vine" under Habit (general appearance) to find other native vines of Tennessee. If none of these vines are the vine in your backyard, then it is likely not a native. Your best bet for identifying it is to take photos of the fruit and the leaves on the vine and submit them to one of the plant identification forum links found on our Plant Identification page.
Below are photos of the flower and the foliage of Passiflora incarnata from our Image Gallery. Unfortunately, we do not have photographs of the fruit.
