The Pomegranate has come home, as the office is closed, and I didn't want to run the risk of him not lasting from one watering trip to the next. 

Now residing in the greenhouse - outdoors, but unheated.  We've had a particularly warm March and April so far.  Must find out what temperatures Puglia gets down to, as I know there is one growing outdoors there all year round.  Will give a good idea of its frost hardiness.
