Daintiness, I suggested on an earlier thread that your clematis could be Justa.
You say it cannot be Justa because Justa is ' a viticella ' and they have smaller flowers.
Wrong, Justa is not ' a viticella ' it is a member of the Viticella Group, in which several cultivars have larger flowers.
I still cannot accept that even Lidl would sell HFYoung as a ' Summer Flowering Clematis '
HFYoung flower size 10 - 22 cms.
