I didnt know that either. My bay has survived the winter despite being

yellow, but the rest look ok. It had no protection throughout the
winter, so maybe I have just been very lucky.

They aren't as tender as all that - mild frosts, like the occasional
drop to -10 Celsius, aren't a problem. *Below that, they start to

Well, make up your mind.

Earlier in this thread you stated;

"Bay is not very hardy, and used to go brown every year in Cambridge,
but this winter wasn't particularly hard here. Once the bark freezes,
the top will die completely. But they can regrow from fairly deep
roots."

I would have thought that an air temperature of -10C is quite a sharp
frost, not a 'mild' one (whatever that means).

Is there a definition of exactly what "hardy" means, in terms of
ability to survive cold winters?
