That would have to be the Nandina 'Heavenly Bamboo' planted by previous owners of the house we bought 6 years ago. All are too well established to remove without killing everything around them. They send out thousands of suckers off their roots that seem to even run underneath the cemented pathways in my garden out back. I've given up removing then and just shape the 4-5 larger ones to confine their size and weed whack all the suckers off to ground cover level as needed. It's all I really CAN do.
Those before me here also planted out some ground ivy I'm quickly growing to hate. Love it inside the defined bed it was clearly planted in, but starting to have trouble keeping it INSIDE the bed. The bed is bordered with 5-7" large irregularly-shaped river rocks. May have to change out the rock edge for a low wall of pavers in future. I pull runners that jump the rocks up and lay back inward in the bed to redirect, b ut occasionally it creeps out underground and wants to move into my BACK yard! Cannot have that!
