Neal ....
I had a bare root rose, years ago, that ended up getting soaked in a 5 gal bucket, without any water changes, for over a month because I became very ill almost the day after I brought the bare root rose home and simply could not get it potted up ! It even bloomed ...
Of course, I was living in San Diego at the time, better known as "Rose Heaven".
Roses are tougher than we think they are.
Zuzu ... 'De la Grifferaie' is a strong rose up here. There is a guy who has a home down on Main Street and he has a whole hedge of D la G that he whacks back every year so that tourist walking past is home during the summer don't get grabbed by a wandering cane. It's a beautiful rose.
