I put this on Name This Plant and no one knew what it was. It is a vine with heart shaped leaves. This bulb is 3" high and almost 4 " in diameter. It blooms but don't have a pic of it.
Does it make potato like fruit in late summer? If so, my guess is Tater Vine, also known as Dioscorea bulbifera. It's a very cool old passalong plant in the deep south.
Donna, I know what the potato vine looks like. I have had all I want of that plant. They are very invasive where i live. This leaf is much smaller. I will post later with a pic of the leaves.
The heart-shaped leaves make me wonder if you might have heartleaf peppervine, in the genus Ampelopsis. As with other peppervines, the fruiit is peppercorn sized and dark purple. It's a noxious weed.
