It should start growing again nearer spring. They flower on the previous years growth, so it might not flower this year, depending on when it was cut back. If it does flower this year, you can prune it back straight after flowering if you want to restrict its growth. If it doesn't flower this year, then prune it by early summer so that it can put on new growth, which will carry next years flowers.
