A number of years ago, a friend gave me a peony bush from her yard. I planted it in a flower bed, and it grew. However, I didn't like the color of the flower. But, I didn't do anything about it. However around five or six years ago, I did. I cut the thing down and dug up the root. Now, if you don't get all of the root, it will come back.
It came back the next year. I cut it down and dug up the root again. Two years later it came back. Now last year, I completely redid the bed. The major renovation involved raising the bed six inches. Before raising the bed, I dug out all the plants including the peony.
I redid the bed and it looked very nice last year even if I do say so myself.
HOWEVER, this spring guess who showed up? You guessed it.
 I'm incline to dig it up again but  because it has been is so stubborn, maybe I should let it grow.
What should I do? Keep digging it up, or live and let live.

I'm Baaaack!!
