I think it a huge spreader as well. And a big plant.
They say with horseradish and comphrey, once you have it, you always will!
Took years to get rid of one I had too close to a veggie garden (planted with all kinds of herbs). I was just learning.
Dug it up. Ha! Back again. Dug it up again. Ha!
Moved a small piece across the brook up the hill a little and have let it go. Now it is about 4 ft across and 4 ft tall. But it is ok there.
I use the leaves on the compost pile. And cut small leaves to freeze for winter use.
