Hi everyone
I bought this clematis last October and it has overwintered in my unheated greenhouse. It has been outside for the last 4 weeks and I will be planting it shortly. Can anyone tell me a bit about it because I am worried that it may not be fully hardy. Magnus Johnson describes it as evergreen and says it flowers in the wild in Dec-Jan but I would appreciate some more information about it. I have a cirrohosa var purpurascens freckles which has survived in my garden for the last 3 years (and flowers every year) in a sheltered spot so I am optimistic this may also survive.
Any advice much appreciated.

Hi Aidan,
My experience with this clematis has not been very good.
This is not to say you will have problems but on the two times I have tried to grow this plant it has died.
I found it was not evergreen here in the UK, even down here in the south and this was with it kept in a cool but relatively frost free environment over the winter period. When the time came to start growing again it used to start producing short green shoots which would get to about 1cm in length and then they would collapse and the plant would die!
It was planted in a very large container using a mixture of compost and John Inness No.3 and had put on a tremendous amount of growth the previous season (so at face value the medium seemed acceptable). I kept the medium moist but certainly not wet during the winter but by its nature John Inness No.3 is quite a heavy medium and thus stays quite cool and relatively damp.
I think by my findings it prefers extremely well drained soil as it seemed to grow well in Bleddyns mix of medium which has relatively no soil content.
