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.

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.

Visitors to this page have left the following comments| Caleb M. | Jan 21, 2009 | Rob - Your 'Powis Castle' artemisia look diminutive next to those that grow here in southeastern Missouri (I know - your's are still new). They get huge - up to six feet across, although not more than four feet high. They look dreadful in the winter but you can whack them way down in spring, rather like a buddleia. I had a pleasant occurence with these artemisias last summer - a very dark morning glory trailed across and through one of my biggest plants. The combination of silky purple morning glory on a setting of silver artemisia filigree was stupendous!
Cool contrast - thanks for sharing! |
