When I worked landscape in college, we used to dig up plants the owner referred to as Ille Agnes. She said it was a "noxious weed" that refuses to die. Since then I have seen the plant in highway rights of way. It's big and gangly but seems to live through anything--including the current drought we have here in Bama. I'd like to plant some in my new landscaping as a border but I can't find it. I have searched the net. Maybe I have the wrong spelling or even the wrong name. It's tall (8-12 feet), thick (6-8 feet), light green pepperminty color with about 2 inch leaves growing extremely thick all over the plant from gound to top. Same color year round. Anyone know what this is more commonly refered to?
