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... |
Positive | On Apr 19, 2012, vossner from East Texas, Has bloomed reliably for two years in a row though sparingly. Grown in a pot with rosa S. de la Malmaison. would probably do better planted directly inground and I may eventually transplant, but not on my to do list right now. |
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. |
