Along roads in the campus of Hokkaido University, we can see a lot of pineapple weed. You may see this species in a field trip of my lecture, HUSTEP (Plants and Plant communities in Japan, flora list). [1] on a roadside in the campus of Hokkaido University, Sapporo, on June 14 2007. [2-4] at a small arable land, N24/E1, East Ward, Sapporo, on July 18 2012. [5] on an unpaved parking lot, N17/E1, East Ward, Sapporo, on May 31 2019.
