Black-eyed Susan is one of the few flowers that rewards low effort in a way that feels almost unfair. Sow it, keep it in the sun, ignore it. It germinates readily, flowers in its first summer, and carries on through drought and heat that has the rest of the border sulking, standing 2 to 3 feet tall with the classic golden-yellow daisy petals ringing a raised, dark brown-black center.
How black-eyed susan fits zone 7's season
