Resurrection of Pink Serissa

At the end of last year, I got a lovely little Pink Serissa (Serissa foetida). I was just beginning to consider how to train it as bonsai (left picture), when my dog Bella ate it to the ground. The stump of the main stem soon rotted away and I lost all hope for the plant's survival, when suddenly a leaf bud sprouted from something that looked like a surface root. Look at this plant now (right picture)!
