Some plants are real winners while others have not performed well in another year of infrequent rain. Here are some of the winners that have impressed me and why:
Bottlebrush grass: a 3' grass that grows well in the shade, reproduces from seed very easily and plays well with others.

Celandine Poppy: again, does well in the shade and a good reproducer.

Swamp Mikweed: although it gets 3' or taller, it really attracts insects, provides a great pink color, and reproduces well. It does like regular amounts of moisture though.
The Tooty List:
Irises: not as successful for me, hard time holding their ground.
Black eyed susan: very good plant. Too good in fact. Plant sparingly.
Butterflyweed: really hasn't proliferated and has an awkward form.
