I recently bought this rose and it was blooming a dark bright burgundy red. After a few weeks it stopped blooming in the extreme heat, which I expected. We have had some rains recently and Nur Mahal, like most of my roses, has sent out new canes and has bloomed. The odd thing is that the blooms, the first few of which opened today, are bright medium pink - the color of Belinda's Dream or Bayse's Blueberry. Is this due to the heat, a nutrient overload/deficiency, or just something that happens?
Thank you in advance.
