Answer: Based on your description I am not certain this is a Kalanchoe blossfeldiana variety. As far as I know, most of these are stiffly upright and do not trail. Seeing it flower would possibly help identify it, but without knowing what it is it can be difficult to get it to bloom.
You might have some other sort of related Crassula, there are some that trail such as C. pellucida. Or, perhaps you have some sort of Sedum such as the one pictured next to bottom row at
There are so many different kinds of succulents and they are very "collectible" but, they can be so difficult to identify. You might try asking your local reference librarian to help you find photos of succulents and look for a match. Best of luck with your quest!
