I had replied earlier to this message but it did not appear to post.
My advice is that if you really want to try and
keep this Kordana alive - keep it indoors and
sheltered until the ground is at it’s PEAK best
condition.
I live in Southern Cali and i have probably better
growing conditions yet 3 different sets of Kordanas
have died on me. They are very maintainence heavy
and severely prone to disease, even in the best of
habitats.
These roses are horrible. I’ve had soo much problems
with them and i cannot recommend keeping them for
any reason.
If it is sentimentality you are after - perhaps
a cutting and pressing of the flowers that you
still currently have on the Kordana might suit
you better for a scrapbook memory of your late
loved one. This bush would only disappoint you in
the end if you choose to try and make them grow.
All this in my humble opinion only.
