Neutral	On Mar 7, 2016, coriaceous from ROSLINDALE, MA wrote: Blackened crispy leaves are often due to a common fungal disease called clematis wilt. Large-flowered clematis are more prone to clematis wilt than the species and small-flowered hybrids. http://www.missouribotanicalgarden.org/gardens-gardening/you... Clematis and tomatoes are two exceptions to the usual rule, and are best planted 6 inches deeper than the soil level in the pot. This protects the stem bases from mechanical damage, and helps prevent clematis wilt, whose fungus enters where there's damage. It also helps keep the roots cool. Many small-flowered hybrids are spectacular in flower, and long-blooming. I consider them indispensable, especially th... read more

Positive	On Jun 19, 2011, Elinore from Minocqua, WI (Zone 4a) wrote: This clematis comes back reliably for me and blooms heavily year after year. It usually is a bit on the short side, maybe 4-5 feet on average, but here in far Northern WI (zone 3 or 4a, depending on where you look), I'm just happy it comes back at all! Year after year, by early July it is covered in beautiful, huge, double white blossoms. I just LOVE this one!
Neutral	On Mar 16, 2011, jazzy1okc from Oklahoma City, OK wrote: I noticed recently that, while I have buds on the old growth of my four other other clematis, there are no buds on the one-year-old stems of my Arctic Queen. There is new growth coming up from the roots, however. So, on the advice of a friend who has tons of clematis and is a master gardener, I cut off the dead stems and will train the new growth up trellis. We had a very hot month or two last summer and, although I kept it well watered, it struggled. My friend says she routinely cuts all new clematis down to a few inches of stem the first year. I hadn't intended to do this, but will see what happens. I don't know if this is common for this particular clematis and would like to hear from others.

Positive	On May 29, 2006, CaptMicha from Brookeville, MD (Zone 7a) wrote: I've had great success with this cultiver and I don't have any clematic experience. It likes full sun and the spring weather. I don't know how it'll re-act to our hot summers. It grows in bounds and responds very well to bloom fertilizer. The thick foliage adds a nice contrast to the snow white flowers. In the early spring, I prune off the dead wood, above the last nodes.
