I've had this plant for a long time. It was a gift and I never knew exactly what it was. It had its good times and its bad times and gave flowers a few times, which are little pink to purple and bell-shaped. Now almost all of it rotted, so I transplanted the two parts which were still fine. Happily the plant formed roots on its stem (check the second picture). Due to the thick leaves I would think it's a succulent, but I do not find any picture with leaves similar to this one.
Now, I would like to check how to take care of it best (probably I gave it too much water), but therefore I need to know what species it is.
