Prolly, you only get the flowers if you don't prune. It can grow to 6' plus in one year but I pinch out growing points 2or 3 times,during the summer. This reduces the height, creates a bushier plant and better foliage. You could prune back harder in mid summer to double buds but this plant is quite neat and controllable if,pinched. You can,do this pinching on a whole range of plants grown,for their foliage, e.g. Eucalyptus, cotinus
