TYVM, Janet. I will take more pics in the morning. This plant looks like it's dying all afternoon, no flowers open.
I've given up using luirig.altervista as a resource at all, found so many inaccurate pics over the yrs. The top 3 pics at that link page don't look like C. communis because there's no brown dot on the big yellow things, and the white wisker-like things end in blue balls. The missouriplants pic shows C. communis so well, much bigger flowers. C. erecta also has much bigger blooms.
USDA plants also mentions C. caroliniana but if it's so rare that nobody can get a pic of it to put on reliable databases, it's probably not what sprouted in my yard in about 4 places. I'd discounted that species also for that reason.
