I have six beautifully coloured Celmetis which I bought at the Chelsea flower show about four years ago. They are all different, lost the name tags, but they are oustanding. They are growing over the side of the garage and all in full bloom when last week the one on the end suddenly over a couple of days died completely. All the leaves went brown and dried up and the plant died as if overnight. Any idea what happened and what can I do to protect the rest of these magnificent Celmatis.

Yes I have had wilt more than once on clematis but after a few seasons it seems to stop are great then.

Sounds like Clematis wilt. This plant amazingly will probably not be dead. You will have to cut it hard back though and replant deeper (perhaps up to six inches deeper. This procedure is normal for this problem.
