How to know if Eucryphia intermedia has died of cold

I just managed to get my still-potted Eucryphia planted in the ground in a sheltered spot next the the house just before the three snow storms hit Vancouver. It held all its leaves and yet has them, despite complete exposure to the low temps we've had. I'm wondering if they're frozen on, and this poor Chilean tree will never get a chance to take root.

Can anyone tell me what damage/fatal damage would look like? I feel like a fool for not wrapping the flax and my nice little zone 9 shrublettes in the front yard. Sigh.

Waiting for sun, or even rain,

Boondoggle

If the New Zealand flax burned the eucryphia may have been damaged as well. Wait until spring to see if it is still able to grow and establish.

Marginal subjects should be planted in spring so that problems like this do not occur. It's also important to keep their root areas well mulched so that fatal freezing of the roots is less quick to occur. If a questionable plant can get through a cold period without the root zone becoming and remaining frozen for a long period it can often survive it.

That's why specimens in southern locations surviving a night or two of rather low temperatures does not indicate northern suitability. In warm climates the weather may improve considerably right after the cold nights, or even during the same days as the cold nights - there is no sustained freezing of the soil and roots.

Being deciduous Eucryphia glutinosa is a little hardier - probably to about 10 degrees F. With southern hemisphere plants generally to keep an assortment going well for long periods with destructive frost damage in this region you need to be located in a mild neighborhood close to salt water. If you site has comparatively high minimum temperatures you can get full development of such subjects as eucryphias. If not, there may be recurring losses.
