Q.Itea virginica
Why is this plant sending out shoots away from the main plant? I had this plant in my landscape in Kentucky and Birmingham, AL without this happening. I am now about 30 miles south of Birmingham. Ready to pull these out because they are so untidy. Thanks

Itea Virginica does spread by sending runners out form the plant. You can remove these runners as soon as you see them.
You can try using a good landscape cloth to deter these new shoots.
