where is it planted, it may be that it doesn't get enough sun to flower and this year the weathervmay have compounded the problem?
Also a feed high in potassium will help encourage flowering (potash). On the positive side it may be that is has concentrated on setting dowtwits roots this last year and will reward you by flowering its socks off next year. If it looks healthy this may well be what it's being doing, I sometimes find that shrubs bought in flower then rest the next year causing me too worry only to restart the next.
