There are several very similar red/pink tinged varieties of pennisetum and some are much hardier. Mine has survived being frozen solid in a pot during the beast so I think I'm safe with that one. Can't remember it's name though
For yours I agree with others that it might need some wrapping up in the coldest spells but then it depends on your situation and siting. Sometimes there's a warmer micro climate in London where its very protected.
