I just uncovered Benny Lopez, the found Damask Perpetual from CA, today.
I am happy to report that BL appears small but healthy. There were several small green canes, not just barely green but bright alive green. I fertilized lightly--the organics I am using don't seem to burn my roses, so far--and applied a loose covering of straw for protection from cold winds.
So far, it would appear that Benny Lopez is hardy to zone 5, and any person or nursery offering it for sale or trade can so describe it.
Despite the small size, BL looked to be in better shape than some of my other roses.
