Yes, it is a "clone", which us old farts call "cuttings".
Was it an Auto cutting? If so, that would explain the lack of development.

Now it will just be a matter of developing a good technique that suits your lifestyle and growing environment.
There are thousands of youtube videos and gardening websites that will provide basic info, little tips and tricks, etc..
Goodluck
