One of our Clematis, "Blue Ice", has died back just as it was filling out

ground level.

If it's clematis wilt which has caused the dieback, then you did the right
thing by planting it deeply to begin with. It's a simple insurance policy.
You will, hopefully, get new growth fairly soon. If you don't it probably
wasn't clematis wilt.

I would avoid putting a new clematis in the same position if your "Blue Ice"
has gone to the great compost heap in the sky.
