This is a plant on my back porch that I've had for several years. The only name that I know it by is, "Widow's teardrops". It blooms in these beautiful purple flowers. I take it inside before cold weather hits. In the winter it dies back and there is no plant showing at all. I put it on the top of my freezer where the elderly lady who gave it to me told me to put it in the Winter and I don't water it at all. Then I start to water it in early spring and it comes back out.
Update: Thanks for your comment, Faye about what this flower might be. I think you are correct about what it is. I had tried to find out for years what this plant really was.
Doesn't it make you wonder why it went from Cupid's Bower to Widow's teardrops? Unfortunately, the lady has passed away that gave it to me and I cannot ask her.
