Big blue sea holly

Question

Some of the big blue sea hollies I bought two years ago are healthy with good leaf growth but have not flowered. Am I doing anything wrong, will they flower another year? Any help would be very much appreciated.

Make sure you do not fertilizer these plants. To much nitrogen can cause lots of leaves and no flowering.
