Question:
My Morden Centennial shrub rose is producing pale pink blossoms this year. Since it was planted 4 years ago, the flowers have been a much darker medium pink, the characteristic color of this variety. The flowers are being produced from stems from the same canes that previously produced darker flowers.

Why? How can I get back to the original color?

I am a master gardener working to educate the public including children in sound gardening principal. However, I am stumped by this color change.

Replies:
Dear Jane,

There are a few possibilities, but I would be inclined to consider what the soil pH is and whether the variety has a recommended pH for optimal growth.
