Crepe Myrtle - Flowers in the Sky

With two Jack Russells and a collie that sometimes enjoy digging, I've found that I can't effectively grow flowers in my back yard.

So I have several crepe myrtle, which look to me like "flowers in the sky" ... They allow me to enjoy the beautiful colors of the spring and summer seasons, but the flowers are too high for paws to reach them.

In my back yard, I have one purple crepe myrtle and three white crepe myrtle, and in my front yard and side yard I have four pink crepe myrtle.
