Will the mystery plant remain unsolved?

I’m beginning to think we’ll never know what the mystery plants are. The grey weather has descended. Some of the leaves are showing a dusty white rust of doom. But still the various mystery flowers open a bright yellow. Still they are foolish enough to keep setting fruits. And at least one green Agapostemon bee is finding shelter in the flowers. (Maybe some fruit flies, too.) So enjoy the mystery while it lasts.
