The white flowers of the phlox are complemented by the silvery tones of the artemesia in this fragrant combo that is especially pretty in moon light. The fine texture of the artemesia gives a delicate, lacy look to the combination while the frilly appearance of the phlox’ flower heads introduce a romantic note. The rounded growth habit of ‘Powis Castle’ provides a nice contrast to the upward thrust of the flower-bearing phlox stems. By including three different phlox’ the bloom period can be extended through the summer. ‘Powis Castle’ will look good all season. Plants do best in sun and well-drained soil.
