Black eyed Susan

More yellow....  like sunshine.   Rudbeckia fulgida - Astraceae family.   Fulgida means shiny or glittering in latin.

Yellow flowers with coarse dark green foliage.  Gardeners feel it looks best when grown in a big circle around a tree.  I can imagine the pretty picture it would make.  But even otherwise the flowers look pretty and they have this brown-black centre and thus the name Black-eyed Susan.
