My bright pink phlox has come up but they are not pink this year - but pastel blue. What could have happened? Perhaps the buds were frozen during a recent snowstorm? Will they return to pink next year?? Thx

Many Hybrids can and will see some color changes and the flower colors can even change throughout the same growing season.
