Bad weather causing damage in all sorts of places this week - sorry to hear about the fallen trees, Wiveka.
I would think that some hardwood cuttings, around 30cms long, buried to half their length in a trench ( under a hedge, perhaps, where the soil is still quite warm) and by next spring there may well be root growth.
I would also hope that even the crushed main plant might be able to regenerate from its base next year - good luck!
