How to Get Rid of Gooseneck Loosestrife
Indianapolis residence - I inherited some of this invasive plant, thought I had dug it all out a couple years ago, but this year it's back alongside the house like gangbusters!

Yes, it is known for that. Any small pieces of the root will result in this plant coming back.
Persistence is the key with getting rid of it. Dig it up as best you can and then treat the area with boiling water. Please note that boiling water will kill any plant that it comes in contact with, so don't get any on any plants you would like to keep.
After this, keep a sharp eye out for any stray sprouts and pull these as soon as you spot them.
If it is an area you don't mind fallow for a bit, you can also smother the plants with thick layers of newspaper or cardboard.
