Frost! - what died and what survived?

A lilac bush growing on the top of a bank actually came of the ground, roots and all, because of the weight of the snow.

Also in Oxfordshire...many, many yuccas around here are dead. Mine has a new shoot! And a very few did survive and are now flowering. I hoped mine would, but it now has to start over.
Cordyline in a pot is still alive but a lot of dead leaves - it was protected from the morning sun.
And the other thing I have seen is that a lot of ash trees kept their seeds on and came into leaf very late.
Not sure about my potted bay bush.

It looks from comments so far as if it is non-native plants that have suffered most. Have other people found that too?

A dead bay tree, variegated myrtle bush, New Zealand Fern tree...all gone. Our large Hebe Kirkii survived but a smaller one didn't. The Ceanothus, Sacred Bamboo and Rowan trees struggled but appear to be OK now. Our Silk Tree survived - although it took a long time to come into leaf and we were beginning to get worried. We live on the Staffordshire/Chesire border.

Should have said I'm from Cheshire.

I lost 2 cordylines and a Californian Lilac (can't remember the Latin name). Both the cordylines were well established, about 10 years old, and my DH decided to just cut them down and leave the stumps. Have just noticed that on both of them I have baby cordylines making an appearance at the base of the stumps.

I lost my Rosemary which was a replacement for the one I lost the previous winter! Several other plants which I thought I'd lost have struggled back to life - hooray! (In Cheshire)

I lost my lovely bay tree - It was in a pot, perhaps would have been safer in the garden. Here in Norfolk lots of cordylines are looking very sad, but do not despair....We dug up a cordyline 2 years ago and little plants keep appearing from a root which we obviously missed, you might just be lucky and be able to extract one and start again. Good Luck

Dead bay trees and a nice Viburnum bodnatense. i was told that bays have suffered terribly - havent replaced it yet might have to use the dried leaves(yuk).

Lots of dead Cordylines and other usually hardy palms in Oxfordshire.
