Since Will Richardson alluded to a "non-natve" cudweeds in the sidewalks
that American Ladies - V. virginensis can host on, I have to add that we
have a native Cudweed in Seattle, "Cotton Batting Plant" - Pseudognaphaliu=
m
straminium <https://www.inaturalist.org/observations/56945727> (formerly
Gnaphalium chilense / P. chilense) that grows in the sidewalks, and is one
of our natives best adapted to growing in various disturbed, and bare soil
situations, along road, and railroad edges, sidewalk cracks, industrial
areas, and shows up, uninvited, into people's rockeries in their gardens.
I have started planting it in areas where my weeding around natives, leave=
s
bare soil that is hard to keep the alien weeds out of (Especially one
native Short-styled Thistle - Cirsium colony
<https://www.inaturalist.org/observations/55550214> I started). I also
favor this cudweed species in hopes that one of our rare visiting American
Ladies will someday lay eggs on it. I have to guess that the cudweed that
you refer to Will, is the same one we have in Seattle's sidewalks, and tha=
t
it is also native in San Francisco.
