Answer: Europs is a shrubby perennial with the potential to grow to 6' tall if not controlled. To keep the plant in shape, trim back stems as they finish flowering, all through the spring and summer months. You'll discover that the more you trim, the more flowering branches the plant will produce.
Wait until new growth begins in the spring and selectively cut back some of the stems. Don't remove more than one-third of the branches at any one time or you'll send it into shock! It will take some patience over the next few months, but if you cut it back at regular intervals you'll have a more compact plant, without sacrificing bloom.
