Kill it, eat it, leave it be?
Okay, it grows rapidly, it tries to take over everything. It doesn't get that tall (based on last year). It's very soft and furry. The roots snap off even if I try to carefully dig them out.
So, what is it and what do I want to do with it? Can I eat it? Should I make into a salve to cure dry skin? Can it kill Bermuda? Should I declare war on it?
