Potato Plant?

Potato Plant?

I live in zone 5. My neighbor just came back from Florida and gave me some bulbs she purchased there. She said they are called "Potato Plants" and grow as a vine. She gave these to me because I've been looking for something to grow along my fence to provide some privacy. She knows little about these vines herself and is going by a plant she saw in a nursery in Florida and what the worker told her about them. She's not sure if they will do well in zone 5, if they flower, etc. Does anyone have any info on these plants, maybe those of you who live in Florida and the surrounding area? I also heard these may be toxic to dogs? I have a dog and don't want to plant them, if that's true. Since I don't know what the plant looks like, it's hard for me to look online and gather information, since I don't know if the pictures I see of such plants are what I have. Thanks so much for any little bit of info you guys can give me.
