I'm not a big fan of the stuff and I'm trying to eradicate it on my place.
I see no browsing of it and it colonizes and chokes out anything along edge areas that have light shade. It also spreads from the edge and out into plots. It grows in those areas that are good raspberry habitat...I'd rather have raspberries.
I've heard it's pretty good stuff for your home garden. The tubers can be left in the ground until you want to harvest, like carrots. I haven't ever heard of getting browse on them.
