I pulled this out of my yard today. I still need to figure out how to get out the rest of the root. I have a 8' deep hole in my front yard and the darn thing is still entrenched.
For a little size perspective.
Sometimes they've lived so long, they will never die.
But I will say the awesome Irises and Lilac bush make the yard totally worth it. :)
I cut a few fresh lilac stems for the house - it is AWESOME.
