Yes this rose does tolerate some shade. I have it in part sun and it blooms non-stop for me and the blooms do not "burn" either. I think the deep dark reds do better when they are not in the sun all day.
My Black Ice is about 3 ft. tall now - it is two years old. It is also own-root. No disease problems. I plan on propagating more of this rose. It's my daughter's favorite - the dark red blooms are gorgeous.
Thanks for the info. Mine is also very clean which is great as I have stopped spraying. If your daughter really likes the deep red roses, you may want to look at another Floribunda named Malicorne. Ashdown sold it until they closed but check Rogue Valley to see if maybe they have it as they bought the Ashdown inventory.
