I found this video on their history interesting.

In particular, I did not realize that they were brought over by settlers. Likely on purpose as a food source/herb then spread with western expansion. Another thing I remember is that he says there are accounts in China of roots getting much longer. 10+ feet IIRC, compared to 2 claimed in this article. Although that's a bit hard to believe. I guess it is used in traditional Chinese medicine.
Of course now they are just seen as a weed. I guess I have mixed feelings The yellow flowers themselves dont put me off but seeing large patches of them after going to seed dont look good. Unlike many here probably, I do like a pristine lawn but even still I don't think the flowers themselves are a pure eyesore.
