One of my hanging plant's name I don't know, can you identify it? here are its pictures:
Leaves Front Side:
Leaves Back Side: (Purple side)
This is Tradescantia zebrina (previously known as Zebrina pendula), although it is often confused with other Tradescantia varieties such as T. fluminensis.
The plant you ask about with purple and green leaves is called "Wandering Jew" in my neck of the woods.
