temporary fields in different parques of Leipzig, seemingly as an offer for pollinating insects. Also consisting of https://www.inaturalist.org/observations/31187415
Earlier observations, same plant, other locations: https://www.inaturalist.org/observations/28176253, https://www.inaturalist.org/observations/28687826
(I'll tick the cultivated check-box when the plant is IDed to species, so it stays in the needs-ID list until then).
