It is winter hardy — not clear whether plant or seed — at least as far north as southern New Jersey. So is Callirhoe involucrata. We have both in our garden.

There are also lots of native Cirsium species, including some endangered ones. Pitcher’s Thistle (C. pitcheri) in the Upper Great Lakes is endangered by specialist beetles that were brought in to control the weedy Cirsiums. Crazy, huh?!

I guess they look lovely when you are not a farmer. The Texas thistle looks a lot like the Canada thistle cirsium arvense and this one is well know in many states. It is considered a weed, a noxious and invasive one at that. It is a great survivor that continues well even with state laws that will fine owners who do not get rid of them.

The PlantNet app identified your yellow composite as Desert-chicory, genus Pyrrhopappus, species either pauciflorus or carolinianus. PlantNet and iNaturalist are both better than Seek according to the NYT Wirecutter review (even though Seek is a ‘user friendly’ version of iNaturalist, it doesn’t seem to work as well).

I wonder if that’s a fluke, or maybe some of the pollen gets attached to the spider’s web and that draws a little extra traffic? Could a pollinated spider be a well fed spider?

I suppose it is possible for spiders to be accidental pollinators. That was a crab spider, and perhaps it carries pollen by static cling (?).

I first encountered it, growing out of the sand and in bloom many decades ago near Cape Hatteras. Then, a few yrs ago there was one growing from the joint between the curbstone and sidewalk, across from the local steel mill. It bloomed continuously from mid-May to mid-Nov.
