'Joanne',

It will bloom again in September. Prune lightly in the spring. The
seed heads are decorative and are best left in place. It is not usual
to deadhead clematis.

Emrys Davies.

Now that my Nelly Moser has finished flowering, if I cut off all the
fluffy
seedheads and give it a trim, will it flower again later on. Or do I
just
leave the thing alone?

Thanks
