Thank you Cindi and Porkpal. I will give it another try with the water method. I moved trees and bushes and when I tried to dig this one out I was surprised that it was so hard.
The realtor told me I had to slim down the gardens and make the landscape simple and I just could not just cut good plants down and kill them. This is the last need to go plant to make the front the grass simple front entrance garden and it is a plant I really want.
