I'm not holding my breath. Lost a 15 year old specimen in my backyard - well when I say lost, its left with nothing but a few pretty dead but hanging on leaves, the rest fell to the ground in the recent wind having been bitten by the frosts. We had below -10 for the first time in about 20 years so its no suprise. No idea if it will regrow - going to wait and see.

I think it has been a bad winter for cordylines!! I saw one the other day about 12' high and all dead at the top it is such a shame. I hope yours comes back all you can do is wait and see.
