'Powis Castle' is an artemisia that I would not part with, but it does not belong as a central player in garden beds. Used as an edge-of-area plant [and given an occasional careful Roundup spray along edges where it oversteps boundaries] it makes a lush mound in sun, and, once established, has little need for watering.
I love this plant. It has a rather pungent odor if you touch it, but otherwise it has held up well in our 5 year drought, (it has been a month since we have received even a sprinkle, let alone a shower) and it remains as whispy as ever. Only looks scraggly in early spring and its branches can be cut back to any degree to tidy it up.
It fills in empty spaces between other plants and will choke out most weeds but even being a slow grower, it can overtake its neighbors. A quick and easy trim of errant branches solves this problem nicely.
Region: Lower Plains
Beautiful gray foliage. Strong fragrance that can be overpowering. This plant was an agressive grower in my yard in the Dallas area, which is great for our hot and humid summers.
