May be. However, protect it now bring it in (or at least out of frost), and hope that the frost has not penetrated too far. If it's not oo far gone, then new leaves will grow back. But . . .
Hardy to about -5 max. Worthy

I usually tie up the leaves to protect the central growing point - but i forgot - so have now wrapped it in a blanket and put a plastic sheet over it - which i wil;l remove once the snow has gone. But last year all of it went brown and i thought it would die - but come late spring it sprouted forth new growth - with many shrubs it is worth giving them a season before digging them out.

Hi All,

Better to use fleece than plastic: The bud still needs to breathe.
