Life cycle perennial (Z5-9)

Cultural notes drought-tolerant

Silvery mound of frilly foliage. We grew our first plant in our Pennsylvania garden, in a raised rock garden area, where it proved longer-lived than the even fluffier variety that's actually named Silver Mound. That one would peter out after one or two years in our garden, but Powis Castle reliably returned year after year, although most winters it would lose some of its woody branches, and some years it would put out foliage on only part of those branches, making for a leggy look until the feathery new growth expanded enough to hide the bare stems. Many years, in my early-season activities planting out small rock garden specimens, I would forget how big around the artimisia gets, and plant them too close – setting the little ones up for a battle for sunlight that they couldn't possibly win.

Houston specimen, planted next to our pond, billows along nicely less than a year after planting

After transitioning to Houston, we once again introduced a 'Powis Castle' into our garden, this one planted alongside our new waterfall pond. It took just a single season for this one to get to a respectable size, and it fits its location nicely. It's always good to see that some of our Pennsylvania standby's can handle Houston's climate. In fact, it should be reliably evergreen here, which is certainly a bonus.

This plant used to grow in our garden, but it slipped away...
