I, too, have had this for a long time. I collected some bits that were kicking around a path in the succulent house in Duthie Park, Aberdeen (around 1982). (Well, they were only going to get walked-upon, until good for nothing.) They did well, off and on, over the years. I have never noticed any scent from it.
I managed to bring some cuttings with me when I moved to Cyprus, but they have sulked, and I have only miniscule bits left. Once upon a time, even these bits would have been rootable, but now they don't want to know
I'm glad yours has perked up!
(This is also known by its syn. C. lycopodioides.)
