Q.Why Do Lilac Bushes Change Shades of Color Some Years?
We moved into our home 5 years ago. I was so excited about our BEAUTIFUL Lilic bush when it bloomed light purple blooms all over. This year something REALLY amazing happened. It bloomed deep purple blooms. The bush is about 9-10 feet tall and about 4-5 feet wide. It’s got deep purple blossoms everywhere! It’s awesome! Why would the bush change color this year?
It is possible for a lilac to have a different hue from one year to the next, depending on pH, moisture and nutrition. While one cannot change the color in a lilac as one could with some of the hydrangea, hue changes are definitely a possibility.
