One of ours looked like a goner, pruned all the dead stuff off, late into leaf, late to flower, just finished... now so much growth it looks better than last year,,,, another one by the fence is just coming into flower but it is a different variety, still nearly a month late....It's happened across the garden things flowering about a month behind..and.because some things are flowering normally I've had some very strange colour combinations that I wouldn't normally have some rathe 'bright'
