My family and I just moved to San Antonio, Texas, and we have this vine growing in our back yard. It climbs vertically but not horizontally, has purple flowers that bloom in late spring through the summer, and has berries that grow in green "cages" and smell like tomatoes. It resembles a nightshade type vine, but I can't identify it based off pictures online. The inside of the unripe berries is hollow, and the seeds kind of rattle around a bit, the ripe berries have very thin skin and the seeds kind of resemble cacao seeds inside the pod, the berries go from green to red as they ripen. I'm not sure how to upload pictures, but the leaves are broad and 3-lobed. If someone can help me identify this vine (or even figure out how to upload a picture, lol) I would be truly appreciative. Thank you in advance!
