North Yorkshire, United Kingdom

I bought three Winter Beauty clematis mail order 3 years ago. I gave 1 to my mum after a year of growing them on in pots . She lives on north east coast and has planted it against a windy fence south facing but in shade some of the day. She has flowers but I don't on either of my 2 remaining. One was planted 2 years ago on trellis fence south facing and had a single flower bud in December but what I thought was flower buds in the leaf joints have not developed. The second one is against a west facing wall in sun from midday in summer and same again - no flowers just immature buds in leaf joints. When this was in a pot in same place last winter It had half a dozen flowers. Any ideas what is going wrong. Thanks
