Crepe Myrtle Turned Colors
We purchased a blooming lavender crepe myrtle late in the year. However, when it bloomed the next year, it bloomed dark pink. I was sad, as I really wanted the lavender. What caused this?

This seems to be a common question; yet, it is one in which many of the experts (myself included) simply remain puzzled about. Most people believe that the color change is based on the pH level or acidity of the soil they're planted in, much like hydrangeas. I, too, would point in that direction. However, the majority of experts disagree and claim there is no scientific proof of this.
Instead, it is believed that this phenomena occurs as a result of two different seedlings having been planted together, or one grafted onto another. Another possibility may be linked to genetic abnormalities.
