    Montanas are all group 1 - prune after flowering finishes but only to keep within bounds.

    The other one must be very new or else badly named as it doesn't appear on this databse which has info on hundreds of clematis - http://www.clematis.hull.ac.uk/

    There's a useful site called Clematis on the Web. You can put in the name and it will give you loads of info.
    Montanas are Group 1 though  :)

  • Clematis Montana Elizabeth is a Montana. 

    Clematis Sugar Sweet Blue is a viticella. 
    How do you know it is a viticella ?
  • Thorncroft Nurseries who are selling this Sugar Sweet Blue  say that it flowers April / May and is Early Large Flowered Group.

    According to this site https://davesgarden.com/guides/pf/go/222484/

    it it is an early flowering viticella - prune as group 3

    it, and therefore I, may be wrong. 🙄 

    I ought to have posted my source ... I usually do , but the frogs were croaking in the garden and I wanted to sit out there and listen 😊

  • Bit of conflicting info here, the Viticella Group ( not viticella ) are pruned hard, almost to the ground in February ( that's if they have been planted correctly ), so I cannot imagine that this plant would then be in full bloom April / May.

    ..it's a seedling from Clematis cadmia, a species...  considering the origin I wouldn't have thought it hardy..

    ...here's some information from the Dutch breeder Tom Hannink… it seems he considers it more in the Florida group.. it produces buds very early but they may not survive bad weather.. he's talking here about a sister seedling 'Delightful Scent'... so I presume it would be similar for the newer one.. pruning seems more for a group 2.. see what you think Richard..?.

  • I know Ton very well and I have much respect for his work, we have exchanged many plants in the past. He has bred several of these scented clematis, much needed in the clematis world. As you say, Marlorena, the only named species in the parentage is clematis cadmia, so I would agree that it should be Group 2.

    It certainly sounds like  a Group 2. I read a couple of pieces of info and there seemed to be confusion about the name - it looked like it had been incorrectly named and was formerly Blue Musk. Could that be where the confusion lies @Richard Hodson ?
