^^Agreed. My tank is overwhelmed with a ginormous tangled mass of hornwort. It grows like crazy
but like Oldfishlady said - it sheds like a Christmas tree. Also, don't bother attempting to anchor hornworts in the gravel/soil because they'll either remove themselves to float around or their bottoms will rot.
