Clematis 'Lasurstern' ?
the top photo also looks like Clematis 'Multi Blue' Dawnsaunt has one if you want to compare yours.

Thanks for the info, I have been to look at 'Dawnsault's picture and yes it looks like it but I must add they are both the same Clematis it started off like the top picture but now it is like the bottom picture, wonder what happend :o/

Did you look at Clematis 'Lasurstern' ?

A lot of the so called double Clematis go on to produce single flowers as a second flush C. sieboldii definitely does it.

Yes, Drc. I did look at 'Lastursten' and now my Mum remembers the name as you have jogged her memory, she is 90yrs old so forgets a few names of plants.
Thanks Owddboggy. For your info too, tell you one thing, there being eaten alive this year + black fly are a pain Grrr! :o( xx Jackie xx :o)
