Powis Castle Silver Sage
Powis Castle sage grows as a dense, dome-like mound of attractive feathery leaves.
Its grey-green color and mounding habit make it a perfect companion plant for many other flowers and ornamental grasses. It looks great in flower beds.
Because it never flowers, it is truly a low-maintenance plant.

Performance
Powis Castle sage grows very well at the Water Wise Demonstration Garden. It is a good plant for sunny, dry locations.
It doesn't look very nice over the winter due to its bare, grey-colored stems, so plant it amongst other landscape plants that have more winter interest.
Maintenance
Stems will die back part way over winter. Cut stems back to new growth in spring.
See in a landscape
This large backyard backs up to a golf course and was previously over 3000sqft of Kentucky bluegrass. Since the backyard received little use, the high water-using bluegrass was converted to Colorado's state grass, Blue grama, and saves about 60% of the water. Many of the plants in this landscape are xeric plants that compliment this native turf well and fit right into the surrounding Colorado backdrop.
Blue grama was a great solution to a tough problem in this landscape. This yard had too much square footage for the homeowner to easily maintain a traditional landscape while committing to lower water use. Since the grass area had infrequent traffic, and full sun, it was an excellent candidate for seeding a blue grama turf that requires less water and maintenance after establishment. Temporary irrigation was installed in order to establish the seed, and will then be removed and the blue grama lawn will receive natural precipitation and watering from a sprinkler only when needed. However, if a dense blue grama lawn is desired, a sprinkler system is recommended. On the far end of the yard is the DIY patio complete with a berm for planting colorful perennials and creating privacy.
