My Maryland (HT) [Madonna x Enchanter] According to E. G. Hill (The Rose Annual, 1913): "My Maryland, a lovely pink, must be kept at 65° or it will go to sleep in mid-season." And from the 35th Annual Report of the New Jersey State Agricultural Experiment Station 1914, "The My Maryland rose succeeds best when the night temperature does not fall much below 61 or 62 degrees."
