A series of coincidences.

First event - Less than 48hr ago, I reset the Max/Min Shed-end.   (Looking worse for wear)
First coincidence - Hard on its heels came word, on Radio, that Shap had a -X˚C (I forget) temperature. 
Second coincidence - I had sense to check the Shed end, see above ^ .
NOW - I had sense to bring in the plant; before WE get -X˚C.
The "plant" purely because I've both lost label and forgotten its name; I suspect it may be a variation on the theme "FICUS".
